Question

A merchant gains 15% by selling an article for birr 150. By how much does he sell it to double his profit?

Answer 1

Step-by-step explanation:

The condition says that

1.15*x = 150,

where x is the cost of the article for the merchant.

Find x, and then evaluate 1.3*x.

My response: 1.15 = 1 + 0.15.

1.15*x is the price the merchant sold the article to get 15% profit.

1.3*x is the price to sell in order for to get the profit 30%, which is doubled 15%.
