Step-by-step explanation:

She worked 50.5 Hours

Step-by-step explanation:

First we have to multiply 7.80x40=312 to find how much she made without the extra hours

Then subtract that from 352.95-312=40.95 to get how much she made with the extra hours

Next you much divide the money made with extra hours by how much she gets paid extra for that time 40.95/4.90=10.5 to get the extra hours worked

Lastly add the extra hours worked to the already known 10.5+40=50.5 to get the total hours worked
