Christopher earns $5.80 an hour and time-and-a-half for all hours over

40 hours. How much did he earn the week he worked 44.5 hours?
a. $240.70
b. $271.15
c. $421.95
d. $281.30

First, we calculate Christopher's straight-time pay for the first 40 hours:

40 hours * $5.80/hour = $232

Next, we calculate how many overtime hours he worked:

44.5 hours - 40 hours = 4.5 hours

Since he earns time-and-a-half for overtime hours, we multiply his overtime hours by 1.5 and then by his regular hourly rate:

4.5 hours * 1.5 * $5.80/hour = $39.15

Now we add his straight-time pay and overtime pay to get his total earnings:

$232 + $39.15 = $271.15

Therefore, the answer is (b) $271.15.
