Final answer:
Jose and Zola's combined gross monthly income is calculated by summing their individual weekly incomes, including Zola's overtime pay, and then multiplying by 4.33 to account for the average number of weeks in a month. The closest amount to their combined gross income is $5,200, which is option B.
Step-by-step explanation:
To calculate Jose and Zola's combined gross monthly income, first we need to calculate the weekly income for each of them and then multiply by the average number of weeks in a month, which is roughly 4.33.
Jose makes $23.50 an hour and works 40 hours a week. Therefore, Jose's weekly income is:
23.50 x 40 = $940
Zola makes $21.50 an hour and also works 40 hours a week at her regular pay. She also works on average 5 hours of overtime a week. Overtime pay is typically 1.5 times the regular pay rate. Therefore, her weekly overtime pay is:
21.50 x 1.5 x 5 = $161.25
Adding her regular pay:
21.50 x 40 = $860
Zola's total weekly income (regular + overtime):
860 + 161.25 = $1021.25
Now, to find their combined gross monthly income we add Jose's and Zola's weekly incomes and multiply by 4.33:
(940 + 1021.25) x 4.33 = $5,200.30
Therefore, the closest answer to their combined gross monthly income is $5,200, which corresponds to option B.
