Answer:

Opening (2 minutes)

Move students into groups of two or three, and distribute the bags of tiles.

Mathematical Modeling Exercise (15 minutes)

 Today, we will model a problem that happens in restaurants every day: moving tables together so that

everyone in a group can sit together. Use the square tiles to represent square tables. One person can sit along

each edge of a table side, no crowding. Our first goal is to find how many people can sit at tables made of

various numbers of square tables pushed together end to end.

 How many chairs can fit around one square table? What is the perimeter of the square if the edge length is

one yard? Record the results in your table.

 4; 4 yards

 If two square tables are pushed together to form a longer rectangular table, how many chairs will fit around

the new table? What is the perimeter of the rectangle? Record the results in your table.

 6; 6 yards

Make sure that each student can connect the square model on the desk to the picture on the classwork sheet.

 If there are twice as many square tables in the new rectangular table, why can’t twice as many chairs fit

around it?

 No chairs will fit right where the tables come together.

 Make a record of the number of chairs that will fit around longer rectangular tables when 3, 4, and 5 square

tables are pushed together to form long rectangular tables.

Mathematical Modeling Exercise

The Italian Villa Restaurant has square tables that the servers can push together to accommodate the customers. Only

one chair fits along the side of the square table. Make a model of each situation to determine how many seats will fit

around various rectangular tables.

Number of Square Tables Number of Seats at the Table

Are there any other ways to think about solutions to this problem?

Regardless of the number of tables, there is one chair on each end, and each table has two chairs opposite one another.

It is impractical to make a model of pushing tables together to make a long rectangle. If we did have a rectangle that

long, how many chairs would fit on the long sides of the table?

Example (13 minutes)

Example

Look at Example 1 with your group. Determine the cost for various numbers of pizzas, and also determine the expression

that describes the cost of having pizzas delivered.

a. Pizza Queen has a special offer on lunch pizzas: $. each. They charge $. to deliver, regardless of how

many pizzas are ordered. Determine the cost for various numbers of pizzas, and also determine the

expression that describes the cost of having pizzas delivered.

Number of Pizzas Delivered Total Cost in Dollars

+

Allow the groups to discover patterns and share them.

What mathematical operations did you need to perform to find the total cost?

Multiplication and addition. We multiplied the number of pizzas by $ and then added the $ delivery fee.

Suppose our principal wanted to buy a pizza for everyone in our class. Determine how much this would cost.

Answers will vary depending on the number of students in your class.

b. If the booster club had $ to spend on pizza, what is the greatest number of pizzas they could order?

Students can use the “guess and check” method for answering this question. A scaffold question might be, “Could they

order 100 pizzas at this price?”

The greatest number of pizzas they could order would be . The pizzas themselves would cost

× $ = $, and then add $. for delivery. The total bill is $.

Answer:

Mrs. Gonzales can buy a maximum of 7 bracelets.

Step-by-step explanation:

A shirt costs $28 total.

Bracelets cost $4.50 each total.

Mrs. Gonzales has $63.50 in all, assuming she wants to spend all of it.

Set the equation, let bracelets be denoted by the variable, x.

4.50x + 28 = 63.50

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 28 from both sides:

4.50x + 28 (-28) = 63.50 (-28)

4.50x = 63.50 - 28

4.50x = 35.50

Next, divide 4.50 from both sides of the equation:

(4.50x)/4.50 = (35.50)/4.50

x = 35.50/4.50

x = ~7.89

However, note that you cannot round up, as you are buying. You also cannot buy .89 of a bracelet, so round down.

x = 7

Mrs. Gonzales can buy a maximum of 7 bracelets.

EX 6: During a snowstorm, a meteorologist tracks the amount of accumulating ... the first three hours of the storm, the snow fell at a constant rate of one inch per hour.

Step-by-step explanation:

The graph representing the data collected by Alang is plotted and is attached at the end of the answer.

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.

Given is a data collected by Alang which gives us the information about the amount of snow on the ground.

We can plot the graph to represent the same situation, Firstly, we will arrange the data in a systematic order. The following table gives the information about the rate of snowfall and the time period.

Snowfall Rate [R]                   Time period [T]

    1 inch/hr                                     2 hr

  No Snowfall                                6 hr

   3 inches/hr                                 5 hr

Now, in the graph -

X - axis represents the time period [T].

Y - axis represents the Snowfall Rate [R].

The graph is plotted and is attached with the answer. It can be seen that for the first 2 hours, the graph is a straight line at y = 2. Then for the next 6 hours, the y - coordinate remains zero (coinciding with x - axis). Finally, for the last 5 hours, it represents a constant rate of 3 inches/hr.

Therefore, the graph representing the data collected by Alang is plotted.
