The entire cost of the car ($21,345) plus the $2,500 upgrade is $21,345 + $2,500 = $23,845.

Question

How do you know find 7% of your total in part A? Show your proportion and work.

Answer 1

To find 7% of the total cost ($23,845), you can set up a proportion:

7/100 = x/$23,845

To solve for x, you can cross multiply:

7 * $23,845 = 100x

166,915 = 100x

Divide both sides by 100:

166,915/100 = x

x = $1,669.15

So, 7% of the total cost is $1,669.15.
