$
725.40
Step-by-step explanation:
Since, every day she works from 6:15am to 4:15pm
this will put her working to 10 hrs a day and subtracting 1 hr break, the total working period would be 9 hrs a day.
And, total working hours per week would be (9*5) hrs = 45 hrs
thus, her total salary per week would be $(45*16.12) = $725.40
55 -10 = 452x2 = 47x7 = 494x4 = 1621 + 1 = 2277- 10 = 67x+30=100 = 70 You gave the answers. ???
