Answer:
8 hours
Step-by-step explanation:
1. Subtract value of tips she got that day
87.05 - 50.25 = 36.8
36.8 is the actual payment for her job that day
2. Divide 36.8 with paid/hour (4.6)
36.8 ÷ 4.6 = 8 hours
18/32 is the same as 9/16 or 0.5625
46 hours
1. add all the hours you've worked (41+49+48+46=184)
2. divide the sum by the number of weeks (184/4=46)
