Question 855566
Gross profit = 20 * $15 = $300
Expenses = $200
Net profit = $300 - $200 = $100
.
(2(10)*15)-(200)=100
(2 [Jess and Lisa] * 10 [the number of students] * 15 [rate per student]) - 200 [expenses] = 100 [net profit]
.
Looks like they'd be better off tutoring at the library or the students' homes.
