Kristen is considering having two different companies create t-shirts for her Math Club. Here are the two company chooses:

Awesome T-shirts charges a $80 up-front fee and $2.50 for each t-shirt, t.
Walden's Tee Company charges a $50 up-front fee and $4.00 for each t-shirt, t.

Kristen needs to order 100 t-shirts. Which company should she choose and why?

Answers

Answer:

Awesome T -shirts

Step-by-step explanation:

They cost less by a margin of $120,meanign better deal

9514 1404 393

Answer:

  Awesome T-shirts; the order is for more than 20 shirts

Step-by-step explanation:

The cost of "t" t-shirts at Awesome will be ...

  A = 80 +2.50t

The cost of "t" t-shirts at Walden's will be ...

  W = 50 +4.00t

These costs are equal when ...

  A = W

  80 +2.50t = 50 +4.00t

  30 = 1.50t . . . . . . . . . . . . subtract 50+2.50t

  20 = t . . . . . . . . . . . . divide by 1.50

If the order is for more than 20 t-shirts, the lower per-shirt price at Awesome will mean the total cost is lower at Awesome. Kristen is planning to order 100 t-shirts, so will get a lower price at Awesome.

Which number line shows 1 to 4 divided into thirds?

Answers

Answer:

Line 1.

Step-by-step explanation:

This is because in order for it to be considered thirds, the third has to equal a whole. Line one goes:

1/3      2/3      3/3

This is split into thirds

The required number line that represents the dividend of the three is the fourth line. Option D is correct.

Given that.
To determine the line that has a dividend of 3.

What is a number line?

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
Line 1 has a dividend of 2,
Line 2 has a dividend of 5
Line 3 has a dividend of 4
Line 4 has a dividend of 3

Thus, the required number line that represents the dividend of the three is the fourth line. Option D is correct.

11. Perimeter = All Sides added together.

Remember there are two of each side with the expression.

Expression: 3b + 3b + b+a + b+ a

To simplify collect all like terms (ones with a common letter or are the same)

Simplified expression: 8b + 2a

You got the expression by adding all sides together then simplifying by collecting like terms.
