Question

Lenna is a software sales woman. Her base salary is $2500 and she makes an additional $40 for every copy of history is fun she sells. Let P represent her total pay in dollars, and let N represent the number of copies of history is fun she sells. Write an equation relating P to N. Then use this equation to find her total pay if she sells 26 copies of history is fun.Equation- Total pay if lena sells 26 copies-

Answer 1

We need to find the equation relating P to N. Also, we need to find P when N = 26.

We know that N is the number of copies of "history is fun" she sells and that she makes an additional $40 for every copy she sells.

Thus, the total additional she receives for selling those N copies is, in dollars:

`40\cdot N`

Also, we know that her base salary is $2500. Thus, her total pay P, in dollars, is given by:

`P=2500+40N`

Now, when she sells 26 copies of "history is fun", N = 26, and we have:

`\begin{gathered} P=2500+40\cdot26 \\ \\ P=2500+1040 \\ \\ P=3540 \end{gathered}`

Answer

Equation: P = 2500 + 40N

Total pay if Lenna sells 26 copies: $3540
