Step-by-step explanation:
20a + 158+6c=you will expand the brackets
= so it is 120+60+48
20a+158+6c=120+60+48
20a+ 6c=120+60+48-158
20a+6c=70
20a divide by 20+6c divide by 6 on both side
a + c = 0.58
She would make about 17.35 because $850 divided by 49 is 17.3469388 rounded is 17.35
Millie will have to pay the $20 back, and as she already has no money, she's now $20 in debt
