Given: - Selling price of the cow = sh 16,500 - Profit made = sh 2,500
Steps to Calculate the Cost Price: 1. Calculate the cost price of the cow. - The cost price (CP) can be derived from the selling price (SP) and profit using the formula: [tex]\[
\text{Cost Price} = \text{Selling Price} - \text{Profit}
\][/tex]
2. Substitute the given values: [tex]\[
CP = 16500 - 2500 = sh 14000
\][/tex]
Steps to Calculate the Percentage Profit: 1. Use the formula for percentage profit: [tex]\[
\text{Percentage Profit} = \left( \frac{\text{Profit}}{\text{Cost Price}} \right) \times 100
\][/tex]
Answer for Problem 7: Haniel's percentage profit is approximately [tex]\(17.86\%\)[/tex].
### Problem 8: Muthuri's Plasma Television
Given: - Cost price of the television = sh 67,500 - Percentage profit = 15%
Steps to Calculate the Profit: 1. Use the formula for calculating profit based on percentage profit: [tex]\[
\text{Profit} = \left( \frac{\text{Percentage Profit}}{100} \right) \times \text{Cost Price}
\][/tex]
2. Substitute the given values: [tex]\[
\text{Profit} = \left( \frac{15}{100} \right) \times 67500 = 10125
\][/tex]
Steps to Calculate the Selling Price: 1. Calculate the selling price by adding the profit to the cost price: [tex]\[
\text{Selling Price} = \text{Cost Price} + \text{Profit}
\][/tex]
