Based on the parameters given, the cost of gallon of gas taken to mow wasn't given and isn't available online, However, the procedure to take to reach the final answer will be broken down in the solution.
Answer:
(400 / 15 - x)
Step-by-step explanation:
Given that:
Targeted profit = $400
Amount charged per lawn = $15
The cost of gallon of gas used will be the expense in this scenario:
Profit = Revenue - expenses
The revenue is the entire amount amount including the cost incurred on providing a Certain service.
Expenses = cost of gas
If cost of gas = $x per lawn
The profit made per lawn equals :
Amount charged per lawn - expense
15 - x
Number of lawns they'll have to mow to earn 400 in profit :
Number of lawns = targeted profit / profit per lawn
Number of Lawns = (400 / 15 - x)
Once the value of x is known, you can substitute into the equation to obtain an exact number for the number of lawn that would have to be mowed to make a profit of $400
