Final answer:
Isaac's total earnings for the week will be $550.00, after working 40 regular hours and 10 overtime hours.
Step-by-step explanation:
The question involves calculating Isaac's total earnings for a week during which he has worked overtime. Isaac's regular hourly wage is $10.00 and he receives overtime pay at a rate of time-and-a-half for any hours he works over 40 in a week.
First, we need to calculate his earnings for the regular 40 hours at his normal rate:
40 hours × $10.00/hour = $400.00
Next, we calculate his overtime pay for the 10 extra hours. Since the overtime rate is time-and-a-half, we multiply his normal hourly wage by 1.5:
$10.00/hour × 1.5 = $15.00/hour
Now we calculate his earnings for the overtime hours:
10 hours × $15.00/hour = $150.00
Finally, we add his regular earnings to his overtime earnings to get his total weekly earnings:
$400.00 + $150.00 = $550.00
Therefore, Isaac's total earnings for the week will be $550.00, which corresponds to option B.
