I ordered 4 new CD's by mail. Each CD costs the same amount and there was an additional $5 shipping charge that brought the total to $33. Write and solve the equation to find the cost of one CD.

$7

Step-by-step explanation:

I ordered 4 new CD's by mail. Each CD costs the same amount and there was an additional $5 shipping charge that brought the total to $33. Write and solve the equation to find the cost of one CD.

Let us represent the cost of 1CD = x

Total cost = $5 + 4x

= 5 + 4x

Total cost = $33

Hence, our Equation is given as:

33 = 5 + 4x

4x = 33 - 5

4x = 28

x= 28/4

x = $7

The cost of 1 CD = $7

Since this is a parallelogram, both bases are equal. You can set them equal to each other to find x:

6+3x=x+14

Subtract x from both sides.

6+2x=14

Subtract 6 from both sides.

2x=8

Divide by 2.

x=4

Hope this helps! :)
