Max is correct when he says he saved 15% altogether
Let assume that each item costs $100
With a 10% discount, he would pay $90
With a 20% discount, he would pay $80
The total amount he bought the items with the discount = $90 + $80 = $170
Without the discount, he would have paid = $100 + $100 = $200
Amount saved = $200 - $170 = $30
Percentage savings = x 100 = 15%
Max saved 15% in total
