A car was bought for 8,000 and sold for 7,000. Calculate the percentage depreciation. Mr. Kwame did maintenance work costing $500 and sold it at an 8% profit. Calculate Kwame's profit and the selling

The car was bought for \8,000$and sold for$$7,000$.

$$\text{Depreciation} = \text{Original Price} - \text{Selling Price}$$

$\text{Depreciation} = \$8,000 - \$7,000 = \$1,000$

$$\text{Percentage Depreciation} = \frac{\text{Depreciation}}{\text{Original Price}} \times 100\%$$

$\text{Percentage Depreciation} = \frac{\$1,000}{\$8,000} \times 100\%$

$$\text{Percentage Depreciation} = 0.125 \times 100\% = \boxed{12.5\%}$$

Kwame bought the car for \7,000$and spent$$500$ on maintenance.

$$\text{Kwame's Total Cost} = \text{Purchase Price} + \text{Maintenance Cost}$$

$\text{Kwame's Total Cost} = \$7,000 + \$500 = \$7,500$

Kwame sold the car at an $8\%$ profit on his total cost.

$$\text{Kwame's Profit} = \text{Kwame's Total Cost} \times \text{Profit Percentage}$$

$\text{Kwame's Profit} = \$7,500 \times 0.08$ $\text{Kwame's Profit} = \boxed{\$600}$

This is Kwame's total cost plus his profit.

$$\text{Kwame's Selling Price} = \text{Kwame's Total Cost} + \text{Kwame's Profit}$$

$\text{Kwame's Selling Price} = \$7,500 + \$600$ $\text{Kwame's Selling Price} = \boxed{\$8,100}$ Therefore, Kojo bought the car for \8,100$.
