Answer:
26%
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...%
Answer: 26%
