SOLUTION
Given the question in the question tab, the following are the solution steps to get the equation
Step 1: Represent the statement using mathematical notation
Base salary is $2500 (Base salary is constant since it does not change)
P represent his total pay (in dollars)
N represent the number of copies of English is Fun he sells
price made per copy of the product is $80
The equation relating P to N will be written as:
![P=2500+80N](https://img.qammunity.org/2023/formulas/mathematics/college/lu05jek0upvhd5hh0v60hr3s3tz1jsdr8a.png)
Part B: Using this equation in step 1 above to find his total pay if he sells 28 copies of English is Fun
![\begin{gathered} P=2500+80N \\ N=28 \\ P=2500+80(28) \\ P=2500+2240 \\ P=\text{\$}4740 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/ju9ec1u1gbgqk2rr07exy6l9bgah8cs6y0.png)
Hence, his total pay if he sells 28 copies of English is Fun is $4740
