 Question from ally, a student: A wholesaler purchased a wheat for $\$150$per tonne.He sold it at$\$170$ per tonne. Calculate the percentage profit to (1 decimal place)if the wholesaler offered a $12\%$ discount on the selling price. What could be the new selling price?

Hi Ally,

He purchased the wheat for $\$150$per tonne and sold it for$\$170$ per tonne so his profit was $\$20$per tonne. You want the profit expressed as a percentage but you didn't say a percentage of what. If the profit is seen as a percentage of his cost then it is $\frac{20}{150} \times 100.$ If the profit is seen as a percentage of his selling price then its $\frac{20}{170} \times 100.$ You should check your textbook for the definition of "percentage profit". Then he had a$12\%$discount on the selling price. What is$12\%\$ of the selling price? Subtract that from the selling price. What is this new selling price?
