Houston has been hired as a salesman. He paid a flat rate of $515 each week and earns an additional $17.50 commission for each sale. If this goal is to make $760 in one week, how many sales must Houston make?
Let "n' be the number of sales.......so we have
515 + 17.50n = 760 subtract 515 from each side
17.50n = 245 divide both sides by 17.50
n = 14 sales
