My answer is assuming to work out the total money spent:
24.95 + 35.99 = 60.94
50% of 49.95 = 24.98
Total = 85.92
Discounted gross price= 73.03
Total net pay = $76.31
The way I worked it out involves working out the discount price before the tax pay and also assumes that the ink price is the price before the 50% discount.
