Answer: Option A
===================================================
Step-by-step explanation:
If she goes with option A, then she works two days for 8 hours a day. In total she works 8+8 = 16 hours. At $7 an hour, she earns 16*7 = 112 dollars.
If she goes with option B, then she earns 5% on the total of 200*10 = 2000 dollars. So 5% of 2000 = 0.05*2000 = 100 dollars is earned.
Option A yields her $112 while option B yields $100. She earns more with option A.
