Jan quint earns $11.00 an hour at her job and is entitled to time-and-a-half for overtime, and double time on holidays. last week she worked 40 hours of regular time, 9 hours of overtime, and 12 hours of holiday time. how much did she earn last week? a. $612.00 b. $720.50 c. $803.00 d. $852.50

Hence, $852.50 she earn last week.

Thus, the correct option is d. $852.50

Explanation:

The computation of Jan Quint earn last week is shown below:

1. Regular wages = Normal hours of worked × per hour rate

                        = 40 × $11

                        =$440

2. Overtime wages  :

In overtime, the per hour rate is half along with the normal per hour rate.

So, overtime per hour rate = Per hour rate + overtime per hour rate

                                            = $11 + $11 ÷ 2

                                            = $11 + $5.5

                                            = $16.5

So, overtime wages = Overtime hours  × overtime per hour rate

                                 = 9 × $16.5

                                 = $148.50

3. Holiday wages:

In holiday wages, the per hour rate is twice of normal per hour rate

In mathematically,

Holiday per hour rate = 2 × normal per hour rate

                                    = 2 × $11

                                    = $22

So, holiday wages = Holiday hours  × holiday per hour rate

                                 = 12 × $22

                                 = $264

So, total wages = Normal wages + overtime wages + holiday wages

                          = $440 + $148.50 + 264

                          = $852.50

Hence, $852.50 she earn last week.

Thus, the correct option is d. $852.50
