Ravi is a software salesman. His base salary is $1800, and he makes an additional $80 for every copy of History is Fun he sells. Let P represent his total pay (in dollars), and let N represent the number of copies of History is Fun he sells. Write an equation relating P to N. Then use this equation to find his total pay if he sells 23 copies of History is Fun. Equation: I| O=0 Total pay if Ravi sells 23 copies: $ の olo
