Answer:
Alex's gross pay for the month is $18/hour x 140 hours = $2520.
The total deductions from his paycheck are:
$180.00 (FICA) + $215.00 (Federal income tax) + $62.00 (State income tax) + $72.89 (Health insurance) + $50.00 (Retirement savings) = $579.89
So Alex's net pay (take-home pay) is:
$2520 (gross pay) - $579.89 (deductions) = $1940.11
To find the percentage of his gross pay that he took home, we can divide his net pay by his gross pay and multiply by 100:
($1940.11 / $2520) x 100 = 77.06%
Therefore, Alex took home 77.06% of his gross pay after deductions.
