Answer:
$3474.25
Step-by-step explanation:
Use the compound amount formula A = P(1 + r)^t. Here r is the rate as a decimal fraction and is -0.15. t represents the number of y ears. P is the initial value of the car.
Then: A = ($15,000)(1 - 0.15)^9, or
A = ($15,000)(0.85)^9 = $3474.25
If you would do this in whole number form, it'll be 40/7.
Answer is C).
One way to find the answer is to multiply the $54 by .30 (which is 30%converted to a decimal). Doing this will give you what 30% of $54 is.
This gives you 16.2
Since the question is asking what 30% off the price is, subtract the 16.2 from the $54.
Note: This is a perfect application for equations of ratios.
50 40
------- = ------- and so 50x = 1200, or 5x = 120, or x = 24 (miles).
30 x
