price paid w/o taxes:= .80(15) + .75(50) + .70(60)= 12 + 37.5 + 42= 91.5price paid with taxes:= 91.5 + (.08 + .05)(91.5)= 91.5 + 11.9= 103.4

15(.2) + 50(.25) + 60(.3) = 33.5 = total discount15 + 50 + 60 - 33.5 = 91.50gst = 4.58pst = 7.32total tax = 4.58 + 7.32 = 11.9$91.50 + 11.90 = $103.40Unless you had to pay tax on full amount -gst = 125(.05) = 6.25pst = 125(.08) = 10total tax = 16.25So $91.50 + 16.25 = $107.75

The total tax is equal to the sum of gst and pst, or 13% (0.13).First item:$15 @ 20% off = $12$15* (1-0.20) = $12$50 @ 25% off = $37.50$50* (1-0.25) = $37.50$60 @ 30% off = $42$60* (1-0.30) = $42Total for the three items:$91.50Total you need to pay:$91.50* (1+0.13) = $103.40
