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.

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
