A certain model of car depreciates 15% every year. The function that models this situation is V = V(0.85)', where V is the value of the car in dollars after t years, and Vo is the initial value of
the car
If Marcos purchased one of these cars for $18,000 and has owned it for 2 years, approximately how
much did the car depreciate each year? Round your answer to the nearest $100.

answer: d. $20

step-by-step explanation:

just took the test

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
