.10d + .05n = 5.25

.10(21) + .05n = 5.25

2.1 + .05n = 5.25

.05n = 3.15

n = 3.15/.05

n = 63

lesya692 [45]

Answer:

$16,500

Step-by-step explanation:

The computation of the amount that should be paid for the car is shown below:

Since the car would be purchased one year ago

And, the value of the car would be decreased by 15% to $14025

So the amount that should be paid is

= $14025 × 100 ÷ (100 - 0.15)

= $16,500
