Problema Solution
Kara purchases a car for $30,000. If V = 30,000(0.9)x gives the value of the car after x years how many years will it take for the car to be worth less than half of its original value?
Answer provided by our tutors
V = 30,000(0.9)^x
x = ?
V(x) < (1/2)*30000
30,000(0.9)^x < (1/2)*30000
by solving we find
x < 6.58 years
