Dallia earns $108.75 for working 15 hours as a holiday helper for wrapping gifts. At this rate how much money will she earn if she works 18 hours the next week? Explain

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 :)
