Answer:

$p =2.15n - 875$

Step-by-step explanation:

Given

$CD_s= n$

$Charges = 2.50$ per CD

<u>Expenses</u>

$E_1 = 875$

$E_2 = 0.35$ per CD

Required

The profit (p)

First, calculate the total income on n CDs

$Total = Charges * n$

$Total = 2.50 * n$

$Total = 2.50n$

Next, the expenses on n CDs

$Expenses = E_1 + E_2 * n$

$Expenses = 875 + 0.35 * n$

$Expenses = 875 + 0.35n$

The profit (p) is:

$p = Total - Expenses$

$p =2.50n - (875 + 0.35n)$

Open bracket

$p =2.50n - 875 - 0.35n$

Collect like terms

$p =2.50n - 0.35n - 875$

$p =2.15n - 875$
