Bella babysits for two families each weekend. one family pays her $20. the other family pays her $22. which expression represents the amount of money bella has been paid after w weekends? select each correct answer. a: 20+22w b: 20w+22w c: 20w? 22w d: w(20+22)

We are given two different payments:

One family pays her $20 per week.

Second family pays her $22 per week.

We need to take w for number of weeks Bella has been paid.

Total payment by first family after w weeks = 20w.

Total payment by second family after w  weeks = 22w.

Total amount paid by both families = 20w + 22w or (20+22)w each week.  

Therefore, option B and option D both are correct options.

B:20w+22w

D: w(20+22)
