Question

Rita is a software saleswoman. Her base salary is $1800, and she makes an additional $80 for every copy of Math is Fun she sells.

Let P represent her total pay (in dollars), and let N represent the number of copies of Math is Fun she sells. Write an equation relating P to N. Then use this equation to find her total pay if she sells 27 copies of Math is Fun.
Equation:
Total pay if Rita sells 27 copies: $

Answer 1

Equation: P = $80N + $1,800

Total pay if Rita sells 27 copies: $3,960

Explanation:

We are given that her base pay is 1,800 dollars and she makes an additional 80 dollars for every copy (N) she sells, giving her total pay of P. Using this information, we can create an equation. We will multiply the money per copy by the number of copies, and then add her base pay onto it.

P = $80N + $1,800

Now, we are given that she sells 27 copies (N) of Math is Fun. We will substitute this into the equation we made and solve for P.

P = $80N + $1,800

P = $80(27) + $1,800

P = $2,160 + $1,800

P = $3,960

Rita would make $3,960 if she sold 27 copies.
