Question

The value of an industrial machine has a decay factor of 0.75 per year. After six years, the machine is worth $7500. What was the original value of the machine?

Answer 1

try to do this problem backwards
lets say the initial value is x
6 years later the value is (x)(.75)^6

Answer 2

.75^6 = .178

Answer 3

if (x)(.178)=7500
then 7500/.178 = x = the initial value

Answer 4

THANK YOU! :D
