Answer:
B)2 benches
Step-by-step explanation:
To break even each month he needs to spend the same amount of money that he earns.
Let's see how much he earns and how much he spends each month:
He earns $175 per bench he sells. If x represents the number of benches he sells in one month, we can write the earning as 175x.
He spends $150 in advertising and $100 per bench, that's 150 + 100x.
So, we need to find out x that makes true the equation 175x = 150 + 100x
175x - 100x = 150
75x = 150
x = 150/75
x = 2
He must sell 2 benches to break even each month
