You decide to make and sell bracelets. The cost of your materials is $84. You charge $3.50 for each bracelet.

a. Write a function that represents the profit P for selling b bracelets.

Respuesta :

Cost of material =$84 Selling Price of each bracelet=$3.50 Let b be the number of bracelets to be sold. Let P be the profit. To get a profit Selling price should be greater than cost price. Profit = Selling Price - Cost price $3.50 * b would give the total selling price. Therefore, P=3.50b - 84
