Answer:
Step-by-step explanation:
Let M = total amount of money earned
M = 12x+8y
To make more than $190, the equation is:
190<12x+8y
Since Trevor is going to scoop ice cream for 20 hours, the equation is:
190<12x+8(20), which simplifies to 190<12x+160.
Isolate x to find the amount of hours that Trevor needs to tutor.
190-160<12x
30<12x
30/12<x
2.5<x
Trevor must tutor for more than 2.5 hours to make more than $190.
