Question

anonymous · Answer

Alan has a tutoring business. For each hour he tutors, he earns $50. In addition to a $75 newspaper ad, his expenses per session include $5 in materials and $2 in transportation. How many hours must Alan tutor before he makes a profit? 

Give the inequality and solve.

Suppose he tutors for x hours so if he's asking for $50 per hour, he'll make
50*x per hour, and that should be greater than (in order to profit) his expenses, which are ($5+$2)*x per each session + $75 (one time fee for newspaper), so the inequality would be:
50x > 7x +75

Now solve the inequality to figure out how many hours he needs to tutor before making profit.
