Answer 1

P=12.95N-750

Explanation

The formula to calculate profit is:

Profit=Total Revenue - Total Expenses

Step 1

a)let

N the number of books

$\begin{gathered} C\text{ost=}C=18.95N+750 \\ Profit=P(N) \\ Revenue=R=31.90 \end{gathered}$

b) now replace ( relates P to N)

Profit=Total Revenue - Total Expenses

$\begin{gathered} P(N)=31.90N-(18.95N+750) \\ break\text{ the parenthesis} \\ P(N)=31.90N-18.95N-750 \\ add\text{ like terms} \\ P\left(N\right)=12.95N-750 \end{gathered}$

so, the answer is

P=12.95N-750
