Question

Sara bought a used car for $10,000. She learned from online that the value of a car depreciated 15% per year. What is the formula for the value of Sam's car after t years? Also, what would be the value of Sam's car in 5 years?

Answer 1

Answer:

Step-by-step explanation:

Value of Sam's car after t years =

=$=10000*(1-\frac{15}{100})^{t}\\\\=10000*(\frac{85}{100})^{t}\\\\=10000*(0.85)^{t}$

Value of Sam's car in 5 years=

$=10000*(0.85)^{5}\\\\=10000*0.4437$

= $ 4437
