Answer:
Gross pay for the week = $603.85
Step-by-step explanation:
Monday pay = (5.4 x 8) + (2.7 x 1) = $45.9
Tuesday pay = 5.4 x 8 = $43.2
Wednesday pay = (5.4 x 8) + (2.7 x 3) = $51.3
Thursday pay = (5.4 x 8) + (2.7 x 1) = $45.9
Friday pay = (5.4 x 8) + (2.7 x 2) = $48.6
Saturday pay = 5.4 x 8 = $43.2
Commission on first $3000 = 0.04 x 3000 = $120
Commission on sales above $3000 = 0.05 x 4115 = $205.75
Gross pay for the week = 45.9+43.2+51.3+45.9+48.6+43.2+120+205.75 = $603.85
