Sarah earned $8.30 an hour for her after school job. Monday, Wednesday and Friday she worked from 3 p. M. To 7 p. M. On Tuesday and Thursday she worked from 3 p. M. To 5:30 p. M. How much money did she earn each week? Each week Sarah earned

$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

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
