Answer:
$137.78
Step-by-step explanation:
If she earns $8.30 an hour for her after school job and she works on Monday, Wednesday and Friday from 3 p.M. To 7 p.M then her pay on
Monday = $8.30 * 4
= $33.20
(note that we multiplied by 4 as there are 4 hours between 3 p.M. To 7 p.M)
Since she works at the same time on Wednesday and Friday then her total earnings on Monday, Wednesday and Friday
= $33.20 * 3
= $99.60
Given that on Tuesday and Thursday she worked from 3 p.M. To 5:30 p.M then her earnings on those days
= $8.30 * 2 * 2.30
= $38.18
(we multiplied by 2 for the number of days and 2.30 as the number of hours)
Hence her earnings in a week
= $99.60 + $38.18
= $137.78
