Answer: 2 years
========================================================
Step-by-step explanation:
x = number of years
Since it costs $650 a year for insurance, she will pay 650x dollars of insurance in total over those x years.
For example, if x = 4, then 650*x = 650*4 = 2600 dollars is paid in insurance.
The expression 650x is added onto the 11675 which is the cost of the car.
Overall, Isabella pays 650x+11675 dollars as the combined cost of the car itself and the insurance over those x years.
Set this equal to 13000 and solve for x
650x+11675 = 13000
650x = 13000 - 11675
650x = 1325
x = 1325/650
x = 2.03846 which is approximate
Rounding down to the nearest whole number gets us to x = 2
She will be able to afford 2 full years of insurance
Note that if x = 3, then,
650x+11675
650*3+11675
13625
Which is 625 dollars over her budget. This shows that she cannot have x = 3 or larger.
