The total amount of money Mark earns after taxes have been deducted,
during a 4-week period is $1256.
The first step is to detemine his total earnings in 4 weeks:
Total earnings = 4 (earnings per hour x total hour worked per week)
4 x 8.75 x 40 = $1400
The second step is to determine the total taxes for 4 weeks
4 x 36 = $144
Now subtract $144 from $1400
$1400- $144 = $1256
