Explanation:
5a.
8 hours a day, 5 days a week. $11.25 per hour.
his base salary will be
8×5×11.25 = $450.00
and he earns commission on sold products.
$750 sales per day (again 5 days a week).
6.5% = ?
100% = $750
1% = 100%/100 = 750/100 = $7.50
6.5% = 1% × 6.5 = 7.5×6.5 = $48.75
he will therefore earn 450+48.75 = $498.75 per week.
5b.
4 weeks per month.
therefore his monthly income will be 4 times the weekly income :
4×498.75 = $1995.00
