Answer:

Step-by-step explanation:

To simplify you will need to do it the same way as in adding natural numbers the variable doesn't change the number

So it's going to be;

9f+10f-12f

(Nine plus Ten is equal to 19)

•The variable remains the same

19f-12f

•So you subtract 12 from 19 which is going to be; 

7f

A new car is purchased for 24600 dollars. The value of the car depreciates at 13.75% per year. What will the value of the car be

liraira [26]

Answer:

The value will be $1,411.20

Step-by-step explanation:

What we do here is to set up an exponential equation to calculate the value.

Mathematically it will look like this;

V = I(1-r)^n

where V is the future value

I is the initial amount = 24,600

r is rate of decrease = 13.75% = 13.75/100 = 0.1375

n is the number of years = 15 years

substituting these values, we have

V = 24,600(1-0.1375)^15

V = 24600(0.8625)^15

V = 1,411.165582454129

= $1,411.20
