What will be the value of the SUV after 10 years of ownership from 2009? If the SUV was new in 2005, what was the original price? Round ($) answers to the nearest whole.

This Q is from an exponential equations worksheet

Solution

the depreciation for 5 years = $11500

the value of suv after 10 years of ownership from 2009 is 19000

the original cost of suv in 2005 may be =53,500

we wll get the original cost by adding 2009 ccost and the depreciation after 5 years = 11,500
