Question

A house purchased for 125,000 is expected to appreciate according to the formula y = 7,000x + 125,000, Where Y is the value of the house after X years. FIND THE VALUE OF THE HOUSE 5 and 10 YEARS LATER.

Answer 1

f(5) = $160,000

f(10) = $195,000

Explanation:

Simply plug in 5 and 10 as x into the equations:

y = 7000(5) + 125000

y = 35000 + 125000

y = 160000

y = 7000(10) + 125000

y = 70000 + 125000

y = 195000

Answer 2

When x = 5, y = 7000 * 5 + 125000 = $160,000.

When x = 10, y = 7000 * 10 + 125000 = $195,000.
