I think we have to calculate the actual prize - the estimations would be too hard.

So:

A: 99.99 * (100%-15%) = 99.99*85%=84,99

B: 95.99 * (100%-12%) = 99.99*88%=84,47

C: 90.99 * (100%-10%) = 90.99*90%=81.89 (this one looks the best so far)

D: 89.99 * (100%-5%) = 89.99*85% = 85.07 (first discount)

85.07.99 * (100%-5%) =.85*07%=80.81 (second discount - this is cheaper than option C).

So, from the cheapest to most expensive: D, C, B, A
