Answer:
$1,411.25
Step-by-step explanation:
The computation of the combined gross monthly income is shown below:
The earnings of Jose = $23.50 × 40 hours = $940
And, the earnings of Zola is
= $21.50 × 40 hours + 5 hours × $21.50
= $860 + $161.25
The total earnings is
= $940 + $860 + $161.25
= $1,961.25
And, the expenses are
= $500 + $50
= $550
So the combined gross monthly income is
= $1,961.25 - $550
= $1,411.25
