If y + 1 is an odd integer what is the next consecutive add integer ?

answer:

-2

step-by-step explanation:

$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
