A new car is purchased for 20,000 dollars. The value of the car depreciates at a rate of 3.7% per year. Which equation represents the value of the car after 3 years?V=20,000(1−0.037)V=20,000(0.63)3V=20,000(0.963)(0.963)(0.963)V=20,000(1.037)3
Q. A new car is purchased for 20,000 dollars. The value of the car depreciates at a rate of 3.7% per year. Which equation represents the value of the car after 3 years?V=20,000(1−0.037)V=20,000(0.63)3V=20,000(0.963)(0.963)(0.963)V=20,000(1.037)3
Identify values: Identify the initial value, depreciation rate, and time period.Initial value P = $20,000Depreciation rate r = 3.7% per yearTime t = 3 yearsWe need to find the value of the car after 3 years, taking into account the annual depreciation rate.
Convert to decimal: Convert the percentage depreciation rate to a decimal.To convert a percentage to a decimal, divide by 100.Depreciation rate (r)=3.7%=1003.7=0.037
Determine formula: Determine the formula for depreciation.The value of the car after a certain number of years can be calculated using the formula:V=P(1−r)twhere V is the final value, P is the initial value, r is the depreciation rate, and t is the time in years.
Substitute values: Substitute the values into the formula.Substitute P=$20,000, r=0.037, and t=3 into the formula.V=20,000(1−0.037)3
Simplify expression: Simplify the expression inside the parentheses.1−0.037=0.963So the equation becomes:V=20,000(0.963)3
Check options: Check the given options to see which one matches the simplified equation.The correct equation that represents the value of the car after 3 years is:V=20,000(0.963)3This matches one of the given options.
