Keith earns $8.60 an hour and time-and-a-half for all hours over 40
hours. How much did he earn the week he worked 47.5 hours?
a. $344
b. $625.65
c. $109.65
d. $440.75
First, we need to calculate how much Keith earns for the first 40 hours:
40 hours * $8.60/hour = $344
Next, we need to calculate how much Keith earns for the additional 7.5 hours at time-and-a-half:
7.5 hours * ($8.60/hour * 1.5) = $91.35
Finally, we add the two amounts together:
$344 + $91.35 = $435.35
Therefore, Keith earned $435.35 in the week he worked 47.5 hours, which is closest to option D: $440.75.
