Question

Mai is a software saleswoman. Her base salary is $1800 , and she makes an additional $40 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 29 copies of Math is Fun.

Answer 1

I mainly need help setting it up, I don't think solving it would be a problem. But if I have trouble I'll ask for help.

Answer 12

That's right.\[
p=40n+1800
\]

Answer 13

What's next?

Answer 14

and then just solve for n? @wio

Answer 15

@wio I forgot to include she sold 29 copies

Answer 16

Yes, now if we let \(n=29\) what do we get?

Answer 17

I got 2960 @wio

Answer 18

\[
p=40\times 29+1800
\]

Answer 19
