you purchase an suv for $26,000. A year later the car is worth only $24,800. If the value of the car continues to depreciate at that rate,
a. find the linear equation that determines the value of the car based on the number of years you own it.
b. when will the car be worth $500?

rate = 1200 per year
Value = 1200t + 26000
b) set value = 500
500 = 1200n + 26000
1200n = 21000
n = 17.5
