Final answer:
The break-even point is when the revenue equals the cost. In this case, the break-even point is 17 lawns.
Step-by-step explanation:
To find the break-even point, we need to determine when the revenue equals the cost.
Michal invests $250 to start the business. Each lawn mowed brings in $15 in revenue.
Let's say the number of lawns mowed is represented by x. So, the revenue is 15x.
The cost includes the initial investment and any other expenses. In this case, the only expense is the initial investment of $250.
Therefore, the cost is 250.
To find the break-even point, we need to set the revenue equal to the cost:
15x = 250
Now, we can solve for x:
x = 250/15 = 16.67 lawns.
Since we cannot have a fractional number of lawns, the break-even point is 17 lawns.
