Question

John has a business selling computers. He buys computers from the manufacture for $350 each and sells them for $600. Each

month, he must also pay a fixed cost of $1800 for rent and utilities at his store. If he sells n computers in a month, which equation can be used to calculate his monthly profit, P?

Answer 1

Answer: p = n (600 - 450) - 1800

Step-by-step explanation: Firstly, you have to account for how much money John is making off of each computer (600 - 350). That factor is then multiplied by the variable "n" which represents the amount of computers sold. Lastly, since this is an equation to calculate his monthly profits, you have to subtract the rent that he is paying ($1800) from the total profit that he made off of selling the computers. Therefore, giving you the equation

P (profit) = n (amount of computers sold) (600-350) - 1800 (rent).
