Question

The value of a computer decreases with its age, until it is worth nothing. A computer that was purchased new (age 0 years) for

$2200 is worth $1540 after 6 years.
The linear function V(x) that expresses the value of the computer as a function of the age (x) in years is V(x)= type your answer_
The value of the computer after 8 years is $ type your answer...
After type your answer.
years the computer will be worth nothing.

Answer 1

v(x)=2200-N*110

the value of computer after 8 years is 1320

Explanation:

at 0 years the value is 2200

after 6 years the value is 1540

we should calculate how much the value of the computer decreases in one year , so we can do an interpolation to determine the value of the computer after 1 year and it is 2090$ . so, 2200-2090=110$ that means in one year the value of computer decreases 110$ so the function is v(x)=2200-n*110

where n is number of years

so after 8 years : v(8)=2200-8*110=1320$
