Answer:

Option D

Step-by-step explanation:

Given the following question:

Product costs: $90
Monthly bills: $2,300
Manufacturing costs: $75

How much profit did they make in one month if they sold 495 units?

In order to find the answer, we first need to multiply the cost of the product by the units sold last month, then subtract the bills/manufacturing costs.

One unit = 90 dollars
495 units sold last month

90\times495=44550
=44550

The company made 44,550 from the product last month.

<u>Now apply the fees/costs:</u>
2,300 dollars in monthly costs
75 dollars in manufacturing costs PER UNIT

44550-2300=42250
75\times495=37125
42250-37125=5125
=5125

Which means the company made a total profit of "$5,125 dollars" or option D last month.

Hope this helps.
