Jeni works from 8:00 - 3:15 three days in a row, only taking a half-hour unpaid lunch break each day. If she is paid $15 per hou
Umnica [9.8K]

Answer:

$101.25  

Step-by-step explanation:

Given:

Jeni works from 8:00 - 3:15 three days

Taking a half-hour unpaid lunch break each day.

she is paid $15 per hour.

Question asked:

what will be her total earnings before tax ?

Solution:

Numbers of hours from 8:00 to 12 = 4 hours

Numbers of hours from 12:00 to 3:00 = 3 hours

Numbers of hours from 3:00 to 3:15 = 15 min =  \frac{15}{60}  (converting min into hrs)

Total numbers of hours = 4 + 3 + \frac{15}{60}

                                        = 7 + \frac{15}{60} = 7 + 0.25

                                        =  7.25 hours

 Unpaid lunch break = half hours =  0.50 hours

Total number of hours for which she is paid = 7.25 - 0.50

                                                                         = 6.75 hours

By applying unitary method :

In 1 hour she is paid = $15

In 6.75 hours she is paid  = 15 \times 6.75 =  $101.25  

Therefore, her total earnings before tax = $101.25
