Answer 1

(1) 8 3/4 % = 8.75 % = 0.0875

So 260000 x 0.0875 = 22750

(2)

10.25 % = 0.1025

So 19870 x 0.1025

(3)

7 1/2 % = 0.075

7 1/2 % of sales = 3750 x 0.075 = $ 281.25

as 281.25 > 270 his gross pay is 281.25

(4)

20000 = 6000 + 7000 + 7000

COMMISSION = 0.0975 x 6000 + 0.11 x 7000 + 0.123 x 7000
