Answer:
The girl earns $22881,6 , and the boy earns $5720,4
Step-by-step explanation:
The girl works 4 out of the 5 days of the week, she works : 4/5 = 0,8
So, she works 80% of the time, and the boy works the 20% left.
If the anual salary is $28602 and that is the 100%, so the girl earns
$28602 * 80% / 100% = $22881,6
And the boy:
$28602 * 20% / 100% = $5720,4
