Mari has spent $18 on startup costs (supplies to make the lemonade cups and advertising)

The break-even point is the point at which the revenue earned just meets the costs

Now, to break-even she needs to make sure she sells lemonade worth at-least $18 on the national lemonade day.

If she manages to make more than $18, then anything beyond $18 would be her profit.

1/3 + 1/5 = 8/15.
