Answer:
Hence, $852.50 she earn last week.
Thus, the correct option is d. $852.50
Step-by-step 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
