A 45,000 car depreciates 12% each year. How much does the car decrease by the end of the first year??

The car depreciates by $5,400 each year (%12 of 45,000)

By the end of the first year, the car will be worth $39,600

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
