30 dollars is the first answer, the second one is explained bellow.

Explanation:

If she earns $12 per 2 hours and $18 per three, it means Theresa receives six dollars per working hour.

The formula is this one:

Y is found when you multiple x (the amount of hours she spends working) times the hourly waive she is given. So, the formula would be y = (a) (x) where y is the total (30 dollars) and a is 6 and x the hours spent at work, 5, giving 30 as a result.
