A music store buys a trumpet for $80. They want to make a 35% profit. How much are they going to increase the price?

They should increase their price by $28.

Step-by-step explanation:

First find out what 35% of 80 is. Do so by multiplying 80 by 35% in its decimal form - .35.

80*.35=28.

This means that they have to increase their price by at least 28 dollars to make a profit.

The new price of the instrument should be $108 - $80 increased by 35%.

Hope this helps :)
