Recommendations
Some salespeople earn a commission that pays them a percentage of the price of the items
they sell. The equation I = hr + ps gives the income of a salesperson who receives an hourly
wage plus commission, where h is the number of hours worked, r is the hourly rate of pay, p
is the percent commission, and s is the dollar amount of the salesperson's sales.
Solve for s in terms of I, h, r, and p.
