Question

When Ava bought her car, it was worth $19,340. It was expected to decrease at a rate of 12.5% each year.

Answer 1

To do this, you must do 12.5% of $19,340, then 12.5% of that sum, and so one 10 times. Your answer:
12.5% X $19,340 = 241,750/100 = $2,417.5.
$19,340 - $2,417.5 = $16,922.5 X 12.5% = 211,531.25/100 = $2,115.3
$16,922.5 - $2,115.3 = $14,807.2
Repeated 8 more times... and you get your answer...
Hope that helps:) Sorry that I didnt give you the answer...
