26%

Step-by-step explanation:

running shoes: 30% off

basketball shoes: 20% off

2 pairs of running shoes + 1 pair of basketball shoes cost

2 * $50 + $75 = $175

The total original price before the discount was $175

Now we find the discounted prices and the total discounted price.

running shoes: 30% off means you pay 70% of the original price

70% of $100 = 0.7 * $100 = $70

basketball shoes: 20% off means you pay 80% of the original price

80% of $75 = 0.8 * 75 = $60

The total discounted price is $70 + $60 = $130

Now we find the actual discount.

Original total undiscounted price: $175

Total discounted price: $130

Actual total amount of discount: $175 - $130 = $45

Now we find the percent that 45 is of 175.

45/175 * 100% = 25.714...%
