Answer:
Wholesale: $37.50
Discount: $7.50
Explanation:
*The wholesale cost of all the bikes they sell is 30%
*Andre wants to buy a bike for $125
*If the bike is discounted by 20%
[tex]\frac{30}{100}[/tex] = [tex]\frac{x}{125}[/tex] (solve for x)
100x = 125 x 30
100x = 3750
(x = $37.50 for the wholesale)
For the discount, we need to find 20% of 37.5
An easier way we can do is to find 10% and to multiply by 2. So, move the decimal to the left of 37.5 and we get 3.75 and multiply by 2
3.75 x 2 = 7.5 ($7.50 the discount)
*
Answer:
$37.50
$7.50

If 120% of a is equal to 80% of b, then what is the value of a+b in terms of a and b?
Answer:
120/100 a = 80/100 b
12/10 a = 8/10 b
10 (12/10) a = 10 (8/10) b
12a= 8b
3a= 2b
a+b in terms of a
b = 3/2×a
a+ 3/2×a = 5/2×a
a+b in terms of b
a = 2/3×b
b + 2/3.b = 5/3×b

Translate the new algebraic expression you created in Question 1 to a verbal expression.
Answer:
Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.
Sarah can use the expression 5(2j + 3 + j) to represent the amount of money they can earn.
Part 1: Writing Expressions
Q1. Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.
25(10j + 18 + 5j)
Your expression is good.
Q2. Translate the new algebraic expression you created in Question 1 to a verbal expression.
Skuttle offered to pay his sister Izzy $25 for every four leaf clover she finds in the woods. Izzy finds 18 clovers but decides to get Roxy’s help. Izzy finds clovers twice as fast as Roxy but they will over all make more money together.
Your verbal expression is good. It refrects your chosen equation.
Part 2: Writing Equivalent Expressions
Q3. Use your knowledge of the mathematical properties to create two equivalent algebraic expressions for the algebraic expression you created in Question 1. Explain how you arrived at the equivalent expressions by showing all your steps and stating which properties you used.
Using commutative property of addition, the expression in question 1 can be rewritten as follows:
25(10j + 18 + 5j) = 25(10j + 5j + 18)
Using distributive property of multiplication over addition, the expression in question 1 can also be rewritten as follows:
25(10j + 18 + 5j) = 250j + 450 + 125j
Q 4. Use substitution to prove your algebraic expressions are equivalent. You may substitute any number for the variables you choose. Show all your work for complete credit.
Now we can subsitute, say 7 for j.
For the first expression, we have:
25(10j + 5j + 18) = 25(10(7) + 5(7) + 18)
= 25(70 + 35 + 18) = 25(123) = 3,075.
For the second expression, we have:
250j + 450 + 125j = 250(7) + 450 + 125(7) = 1,750 + 450 + 875 = 3,075.
Thus, we can see that both expressions are equivalent.
Part 3: Finish the Story
Q5. Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did they earn?
Sarah found 3 + 7 = 10 shark teeth.
John found 10 / 2 = 5 shark teeth.
The total money they earned is $5 x 15 = $75.

A. The right side of the equation should be 6 after subtracting -24 from each side
B. The left side of the equation should be -r after dividing each side by -6
C. The left side of the equation should be -24 + 6r after distributing
???
Answer:
C is the answer
Step-by-step explanation:
1. distribute (multiply) -6 to 4
2. than -r
3. answer would be -24 - 6 = 30
-6r shouldn't be positive. It should stay negative

Rebecca draws a graph of a real-world relationship that turns out to be a set of unconnected points. Can the relationship be linear? Can it be proportional? Complete the explanation of your reasoning.
The relationship will be linear if the points all lie on the same (line , curve ). The relationship will be proportional if it is (linear, non linear) and if the
(curve, line) that all the points lie on passes through the point (_ , _ )

Chris went bowling with $20 to spend. He rented shoes for $5.25 and paid $4.00 for each game. What was the greatest number of games Chris could have played?
A) 2 games
B) 3 games
C) 4 games
D) 5 games
Answer:
3
Step-by-step explanation:
Since he has $20 and spends $5.25 on shoes, that means he will have $14.75 left for games. Since each game is $4, he can play 3 and be at at total cost of $17.25, but if he plays 4 games he will be at $21.25. Therefore, he can play 3 games.
