Fred purchased a used vehicle that depreciates under a straight-line method. the initial value of the car is $10500, and the salvage value is $500. if the car is expected to have a useful life of another 8 years, how much will it depreciate each year?

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
