Answer:

E(n) = n + 5

Explanation:

The profit is the difference between the amount of money received as a revenue and the amount of money spent as expenses.

This means that:

Profit = Revenue - Expenses

Rearrange the formula to solve for the expenses, we get:

Expenses = Revenue - Profit

We are given that:

Revenue = R(n) = 18n

Profit = P(n) = 17n - 5

Substitute in the above formula to get the formula for expenses as follows:

E(n) = R(n) - P(n)

E(n) = 18n - (17n-5)

E(n) = 18n - 17n + 5

E(n) = n + 5

Hope this helps :)

Answer:

E(n)= R(n)-p(n)

E(n)= n+5

Step-by-step explanation:

Since R(n)=18n and P(n)=17n-5 it follows that:

E(n)=R(n)-P(n)

=18n−(17n−5)

=18n−17n+5

=n+5
