Answer:

Part a) 350\ miles

Part b) \$88.5

Step-by-step explanation:

Let

x ----> the number of miles driven

y ----> the total cost

we know that

<em>First Plan</em>

y=0.09x+57 ----> equation A

<em>Second Plan</em>

y=0.11x+50 ----> equation B

Part a) For what amount of driving do the two plans cost the same?

Equate equation A and equation B and solve for x

0.11x+50=0.09x+57

0.11x-0.09x=57-50

0.02x=7

x=350\ miles

Part b) What is the cost when the two plans cost the same?

For x=350 miles

substitute in equation A or equation B (the cost will be the same)

y=0.09(350)+57

y=\$88.5

A new car is purchased for 20300 dollars. The value of the car depreciates at 9.5% per year. What will the value of the car be,
Iteru [2.4K]
The starting value is 20,300, and the value is decreasing by 9.5% each year.

Because it decreases by 9.5% each year based on the previous amount, we use an exponential decay model.

A decrease by 9.5% corresponds to multiplying by 91.5% each year.

We write . We plug in 11 years for t.

A(t)=23000(0.915)^{t}\\\\A(11)=23000(0.915)^{11}\\\\A(11)=7671.18
