To determine how much profit they are making now, let's break down the process step-by-step:
1. Understanding the Variables:
- They are buying 60 comics a month.
- They are selling on average 55 comics a month.
- The cost per comic they buy is [tex]$2.
- The selling price per comic is $[/tex]5.
2. Calculating Total Cost:
- They buy 60 comics a month, and each comic costs [tex]$2.
- The total cost per month is given by multiplying the number of comics bought by the cost per comic:
\[
\text{Total Cost} = 60 \text{ comics} \times 2 \text{ dollars per comic} = 120 \text{ dollars}
\]
3. Calculating Total Revenue:
- They sell on average 55 comics a month, and each comic is sold for $[/tex]5.
- The total revenue per month is given by multiplying the number of comics sold by the selling price per comic:
[tex]\[
\text{Total Revenue} = 55 \text{ comics} \times 5 \text{ dollars per comic} = 275 \text{ dollars}
\][/tex]
4. Calculating Profit:
- Profit is the total revenue minus the total cost:
[tex]\[
\text{Profit} = \text{Total Revenue} - \text{Total Cost} = 275 \text{ dollars} - 120 \text{ dollars} = 155 \text{ dollars}
\][/tex]
Therefore, the profit they are making now is $155 per month.
