Answer: [tex]Profit=\$10.75[/tex]
Step-by-step explanation:
You need to analize the information given in the exercise.
For this exercise you can use the following formula:
[tex]Profit=Total\ Revenue-\ Total\ Cost[/tex]
In this case, according to the information given in the exercise, Max spends a total amount of $2.25 on gas for his lawn mower, but he earns $13.00 mowing his neighbor's yard; so you can identify that:
[tex]Total\ Revenue=\$13.00\\\\\ Total\ Cost=\$2.25[/tex]
Therefore, knowing these values, you can subsitute them into the formula given above:
[tex]Profit=\$13.00-\$2.25[/tex]
And finally you need to evaluate in order to calculate Max's profit. You get the following result:
[tex]Profit=\$10.75[/tex]
