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)^(3)

V=20,000(0.963)(0.963)(0.963)

V=20,000(1.037)^(3)

A new car is purchased for 2020,000000 dollars. The value of the car depreciates at a rate of 3.7% 3.7 \% per year. Which equation represents the value of the car after 33 years?\newlineV=20,000(10.037) V=20,000(1-0.037) \newlineV=20,000(0.63)3 V=20,000(0.63)^{3} \newlineV=20,000(0.963)(0.963)(0.963) V=20,000(0.963)(0.963)(0.963) \newlineV=20,000(1.037)3 V=20,000(1.037)^{3}

Q. A new car is purchased for 2020,000000 dollars. The value of the car depreciates at a rate of 3.7% 3.7 \% per year. Which equation represents the value of the car after 33 years?\newlineV=20,000(10.037) V=20,000(1-0.037) \newlineV=20,000(0.63)3 V=20,000(0.63)^{3} \newlineV=20,000(0.963)(0.963)(0.963) V=20,000(0.963)(0.963)(0.963) \newlineV=20,000(1.037)3 V=20,000(1.037)^{3}
  1. Identify values: Identify the initial value, depreciation rate, and time period.\newlineInitial value PP = $20,000\$20,000\newlineDepreciation rate rr = 3.7%3.7\% per year\newlineTime tt = 33 years\newlineWe need to find the value of the car after 33 years, taking into account the annual depreciation rate.
  2. Convert to decimal: Convert the percentage depreciation rate to a decimal.\newlineTo convert a percentage to a decimal, divide by 100100.\newlineDepreciation rate (r)=3.7%=3.7100=0.037(r) = 3.7\% = \frac{3.7}{100} = 0.037
  3. Determine formula: Determine the formula for depreciation.\newlineThe value of the car after a certain number of years can be calculated using the formula:\newlineV=P(1r)tV = P(1 - r)^t\newlinewhere VV is the final value, PP is the initial value, rr is the depreciation rate, and tt is the time in years.
  4. Substitute values: Substitute the values into the formula.\newlineSubstitute P=$20,000P = \$20,000, r=0.037r = 0.037, and t=3t = 3 into the formula.\newlineV=20,000(10.037)3V = 20,000(1 - 0.037)^3
  5. Simplify expression: Simplify the expression inside the parentheses.\newline10.037=0.9631 - 0.037 = 0.963\newlineSo the equation becomes:\newlineV=20,000(0.963)3V = 20,000(0.963)^3
  6. Check options: Check the given options to see which one matches the simplified equation.\newlineThe correct equation that represents the value of the car after 33 years is:\newlineV=20,000(0.963)3V = 20,000(0.963)^3\newlineThis matches one of the given options.
