(2x-15) + 11x = 180
Combine your like terms in get
13x - 15 = 180
Add 15 on both sides
13x - 15 = 180
+15 + 15
13x = 195
Divide each side by 13 and get
x = 15
Answer: 2.54

Answer:
Step-by-step explanation:
Since the value of the car decreases by a common factor each year, the decay is exponential.
An exponential decay function is of the form

Therefore, the function modeling the car's decay is:

We want to determine the car's value in two years.
When t=2

The value of the car in 2 years will be A(t)=$9109.10
