Answer

After 4 years, the car's resale value is \$7,119.

Solution

To determine the resale value of the car after 4 years with a yearly depreciation of \(25\%\), you can use the formula for exponential decay: \[ \text{Resale Value} = \text{Initial Value} \times (1 - \text{Depreciation Rate})^{\text{Number of Years}} \] Plugging in the values: \[ \text{Resale Value} = \$22,500 \times (0.75)^4 \] Calculating step-by-step: 1. **First Year:** \[ \$22,500 \times 0.75 = \$16,875 \] 2. **Second Year:** \[ \$16,875 \times 0.75 = \$12,656.25 \] 3. **Third Year:** \[ \$12,656.25 \times 0.75 = \$9,492.19 \] 4. **Fourth Year:** \[ \$9,492.19 \times 0.75 = \$7,119.14 \] Rounding to the nearest dollar, the resale value after 4 years is: \[ \$7,119 \] **Answer:** After 4 years, the resale value is **\$7,119**.

To find the resale value after 4 years, we'll calculate the depreciation year by year. Initially, the car's value is \( \$ 22,500 \). 1. After 1 year: \[ 22,500 - (0.25 \times 22,500) = 22,500 \times (1 - 0.25) = 22,500 \times 0.75 = 16,875 \] 2. After 2 years: \[ 16,875 - (0.25 \times 16,875) = 16,875 \times 0.75 = 12,656.25 \] 3. After 3 years: \[ 12,656.25 - (0.25 \times 12,656.25) = 12,656.25 \times 0.75 = 9,492.19 \] 4. After 4 years: \[ 9,492.19 - (0.25 \times 9,492.19) = 9,492.19 \times 0.75 = 7,119.14 \] Rounding to the nearest dollar, the resale value after 4 years will be approximately \( \$ 7,119 \).
