The price of a corporate limo purchased by bob's limos was $42,900. its salvage value after operating for 90,000 miles is $5,577. based on the given annual usage, prepare a uop (units-of-production) depreciation schedule, then enter the annual depreciation for year 5 as your answer. (round all amounts to the nearest cent)

At his particular example, we will use the straight-line method of calculating depreciation. We will also assume that the limo has a useful life of six (6 years) because as per The National Household Travel Survey   a car in the US is driven at an average of 15,000 miles per year so useful life is (90,000/15000=6

Salvage value is the estimated value that Bob is to be paid when the limo is sold at the end of its useful life (6 years).  The salvage value of $5,577 is subtracted from the cost of the limo ($42,900) then divided by the number of years of useful life (6) to get the annual depreciation of $6.220.50 straight from the first year to the fifth year. 

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
