Eric's employer pays him a monthly salary of $1400, plus a commission of $75 for
every fish tank that he sells. Nancy's employer does not pay her a salary. Instead, they
offer her a commission of $250 for every fish tank that she sells.
How many fish tanks would they each need to sell so that they bring in exactly the
same amount of money per month?
