Question

A business owner pays $1,200 per month in rent and a total of $120 per hour in employee salary for each hour the store is open. On average, the store brings in $200 in net sales per hour.

Which equation can be solved to determine the break-even point if x represents the number of hours per month the store is open?

200x – 120x = 1,200
120x + 200x = 1,200
200x + 1,200 = 120x
120x – 1,200 = 200x

Answer 1

Answer: I'm pretty sure it's 200x - 120x = 1,200

Explanation:

Answer 2

200x - 120x = 1,200

Explanation:

The break-even point is when the amount of money he spends equals the amount he earns.

Let's see how much he earns and how much he spends per month:

He earns $200 per hour. If x represents the number of hours per month, we can write the earns as 200x.

He spends $1,200 per month and $120 per hour. We can write it as 1,200 + 120x.

So, we need 200x = 1,200 + 120x

We don't have this exact equation in our options but if we subtract 120x from both sides, we have:

200x - 120x = 1,200 + 120x - 120x

200x - 120x = 1,200

The correct answer is the first equation.
