Hi!
If she worked 18 hours last week and 20 hours this week, then she worked 38 hours in total, because 18 + 20 = 38.
If she earns $6 per hour, and she worked for 38 hours, then she got 38 sets of 6, which you can find the answer to by multiplying 38 and 6.
This is essentially 6 + 6 + 6 +...
38 * 6 = $228
So she earned $228 these two weeks.
Hope this helped!
