Adım Adım Çözüm

1
Calculate the selling price of the generator from the merchant to the retailer.
Selling Price1=₦120,000×(1+20100)=₦120,000×1.20=₦144,000\text{Selling Price}_1 = \text{₦}120,000 \times \left(1 + \frac{20}{100}\right) = \text{₦}120,000 \times 1.20 = \text{₦}144,000
The merchant makes a 20%20\% profit on the initial cost price of ₦120,000\text{₦}120,000.
2
Calculate the selling price from the retailer to the final customer.
Selling Price2=₦144,000×(1−15100)=₦144,000×0.85=₦122,400\text{Selling Price}_2 = \text{₦}144,000 \times \left(1 - \frac{15}{100}\right) = \text{₦}144,000 \times 0.85 = \text{₦}122,400
