Rafael is a software salesman. His base salary is $1900 , and he makes an additional $40 for every copy of Math is Fun he sells. Let p represent his total pay (in dollars), and let c represent the number of copies of Math is Fun he sells. Write an equation relating to . Then use this equation to find his total pay if he sells 22 copies of Math is Fun.

We want a sales function p where c is the number of copies of Math is Fun
p = Price per sale * c + Base Salary
p = 40c + 1900

Now, we want to know Total pay if c = 22
p = 40(22) + 1900
p = 880 + 1900
p = 2780
