Answer:
Penalty: 780$
Explanation:
In this case, the problem states that 15,000 miles is the mileage cap limit per year (12 months), so in 2 years (24 months) it would be 30,000 miles
According to this, Annie drove 35200 miles in 2 years, so she is over the limit by 5200 miles:
35200 - 30000 = 5200 miles
now we know that the penalty over the mileage is 15 cent per mile, or simply 0.15$/mile, so we can actually multiply this amount by the miles exceeded:
$ = 0.15 $/mile * 5200 mile
$ = 780$
And this is the penalty that Annie will pay by the end of the lease
