Question

Members of a school sports team are raising money by selling custom water

bottles at school activities. They plan to sell each bottle for $11. Each bottle
costs them $4. They spend $40 for advertising.
Use n to represent the number of bottles they sell. Multiply this by the money
they make for each bottle, then subtract the advertising cost.
Which expression represents the money that the group raises?

Answer 1

7n - 40

Explanation:

The net gain per bottle is the sale price ($11) minus the costs ($4). 11-4=7

Profits per bottle are $7, with n representing total bottles sold, total sales revenue is 7n.

A fixed expense of $40 for advertising is subtracted from the revenues, and the order of operations makes the net gain 7n – 40.
