a landscaper earns $30 for each lawn her company mows, but she pays $210 per day in salary to her employees. if her company made more than $150 profit from mowing lawns in a 7 - day week, what are the possible numbers of lawns the company could have mowed? select two options.\n□ 12\n□ 37\n□ 54\n□ 61\n□ 80
Answer
Explanation:
Step1: Set up profit - formula
Let $x$ be the number of lawns mowed. The total revenue from mowing $x$ lawns is $30x$ dollars. The total salary expense in a 7 - day week is $210\times7 = 1470$ dollars. The profit $P$ is given by $P=30x - 1470$.
Step2: Set up inequality
We know that the profit is more than $150$ dollars. So, $30x-1470>150$.
Step3: Solve the inequality
Add $1470$ to both sides of the inequality: $30x>150 + 1470$, which simplifies to $30x>1620$.
Step4: Isolate $x$
Divide both sides of the inequality by $30$: $x>\frac{1620}{30}=54$.
