A work-at-home opportunity is available in which you will receive 2 percent of the sales for customers you refer to the company. The cost of your ""franchise fee"" is $710. How much would your customers have to buy to cover the cost of this fee? (Round your answer to the nearest whole dollar.)

We need to collect $710 from the sales of the customers referred by us to cover the franchise fee. But we only make 2% of whatever they spend. If we equate 710 to 2% and solve for 100% we will know what is the total dollar amount they need to spend:

1. This can be solved using a rule of three:

2% = $710

100% = ?

100 * 710 / 2 = 35500

2. Or, It can also be solved writing it down as an equation and knowing that 2% also means 2 parts of 100 or 2/100 = .02

710 = .02*Sales

Solve for Sales:

Sales = 710/.02 = 35500

There is no need to round to the nearest whole dollar because the result is already in whole dollars, it does not have any cents.
