She will earn $130.5 dollars.
First we find how much she makes per hour.
108.5/15=$7.25 per hour.
Then we take $7.25 per hour and she will work 18 hours next week so,
7.25•18=130.5 considering the same rate.
Now we can also make an equation which is,
7.25x=y in which x is the number of hours worked and y is the amount earned.
7.25(18)=130.5 :)
