The Acme Supply Store sells a security system for $2150,00 excluding tax. They

sold 12 systems. If the total profit on these sales was $4824.36, how much did

each system cost Acme Supply? Show your work.

I think the answer is $1,747.97

you're absolutely correct.

each system is sold for $2150, that includes cost + markup, namely the markup is the surplus amount otherwise called "profit".

they sold 12 of those, 2150 * 12 = 25800

they had $4824.36 in profits from it, so if we subtract that from the sale price, we'll be left with the cost of all 12 systems

25800 - 4824.36 = 20975.64

that's the cost for all 12 systems sold, how many times does 12 go into 20975.64? 20975.64 : 12 = 1747.97.
