We can plug in Glen's hours to fin out which one is correct.
Let's try it:
He worked 20 hours for 12 a hour.
Shelia worked 35 hours for 13.50 a hour.
If we multiply them both and it equals 705, then the answer will be correct.
20*12= 240 35*13.50= 472.5 Together, they add up to 712.5. A is not the right answer.
Next one:
I'm going to try D.
25*12= 300
30*13.50= 405
Add them together, and you have 705.
D is the correct answer.
I hope this helped you.
Brainliest answer would be appreciated.
