To find the total amount Abdi earned from selling the radio, we need to calculate both the profit from the sale and the commission he earned on that profit.
-
Calculate the Selling Price:
- Cost Price (CP) = 3800
- Profit Percentage = 20%
- Profit = 20% of CP = \( \frac{20}{100} \times 3800 = 760 \)
- Selling Price (SP) = CP + Profit = \( 3800 + 760 = 4560 \)
-
Calculate the Commission:
- Commission Percentage on Profit = 22.5%
- Commission = 22.5% of Profit = \( \frac{22.5}{100} \times 760 = 171 \)
-
Total Amount Earned:
- Total earnings = Profit + Commission = \( 760 + 171 = 931 \)
So, the total amount Abdi earned from the sale is 931.
