Using Linear Equations
• A machine salesperson earns a base salary of
$40,000 plus a commission of $300 for every
machine he sells. Write an equation that shows
the total amount of income the salesperson
earns, if he sells x machines in a year.
• How much would the salesperson make if 20
machines were sold?
• How many machines would need to be sold to
earn $100,000 for the year?
