Question 1(Multiple Choice Worth 4 points)
Ella purchased a game that was on sale for 12% off. The sales tax in her county is 6%. Let y represent the original price of the game. Write an expression that can be used to determine the final cost of the game.

y − 0.12y
0.06(0.88y)
1.06(0.88y)
y − 0.88y + 0.06y
Question 2(Multiple Choice Worth 4 points)
Write an expression that is equivalent to three over five (3y + 15).

three over fivey + 9
three over five y + 15
nine over fivey + 9
nine over fivey + 15
Question 3(Multiple Choice Worth 4 points)
Which expression is equivalent to one over fivem − 20?

one over five(m − 4)
one over five(m − 100)
5(m − 4)
5(m − 100)
Question 4(Multiple Choice Worth 4 points)
Write an expression for the perimeter of the triangle shown below:

A triangle is shown with side lengths labeled 0.3x plus 24, 5x, and 0.2x minus 15.

10x − 9
10x − 39
5.5x − 9
5.5x + 9
Question 5(Multiple Choice Worth 4 points)
Monica purchased adult and youth tickets for the fair. She bought x adult tickets for $28 each and y youth tickets for $15. Write an expression that can be used to show the total cost, C, of all tickets.

C = (28 + 15)x
C = (28 + 15)(x + y)
C = 28x + 15y
C = 28y + 15x

In order to solve Question 1, we use the fact that y is the original pricing. 1-0.12 is equal to 0.88. Now, when working with SALES TAX, we add the decimal(after converting from percent) to 1.00. Therefore: 1+0.06=1.06. Now, we have the desired, 1.06(0.88y)

For question 2:

(9/5)y +9

In order to solve question 2, we distribute the 3/5 over 3y and 15.

We reach the amount of: 3*3y/5 + 15*3/5.

Now, we multiply everything to receive the answer of: 9y/5 + 9.

Therefore, we have reached the desired: (9/5)y +9

For question 3:

5(m − 4)

We divide both variable and number by 5, as 5 is the common divider of these(besides one).

5m -20

5m-20/5 *5

(m-4) *5

5(m − 4)

Therefore, we have reached the desired: 5(m − 4)

For question 4:

Perimeter is the sum of the sides: 0.3x + 24 + 5x + 0.2x -15 = 5.5x +9

We have reached the amount of: 5.5x +9

For question 5:

All you have to do is multiply the variable by the corresponding cost:

28*x + 15*y= 28x+15y

Therefore, we have reached our answer of: C = 28x+15y

Answer:

1.06(0.88y)

2. (9/5)y +9

distribute the 3/5 over 3y and 15.

reach the amount of: 3*3y/5 + 15*3/5.

multiply everything to receive the answer of: 9y/5 + 9.

Therefore, we have reached the desired: (9/5)y +9

For question 3:

5(m − 4)

We divide both variable and number by 5, as 5 is the common divider of these(besides one).

5m -20

5m-20/5 *5

(m-4) *5

5(m − 4)

For question 4:

Perimeter is the sum of the sides: 0.3x + 24 + 5x + 0.2x -15 = 5.5x +9

We have reached the amount of: 5.5x +9

For question 5:

All you have to do is multiply the variable by the corresponding cost:

28*x + 15*y= 28x+15y

Therefore, we have reached our answer of: C = 28x+15y
