Answer:

D

Step-by-step explanation:

Suppose you buy the first for $30 and next for $20

The 2nd item ($20) will be given 60% discount.

What is 60% of 20?

60/100 = 0.6 * 20 = 12

So, that is off for $12, final price of 2nd item would be:

20 - 12 = $8

Total Cost (WITHOUT DISCOUNT) = 30 + 20 = 50

Total Cost (with discount) = 30 + 8 = 38

What is the percentage decrease?? It will be the DIFFERENCE (50 - 38 = 12) divided by the original price (50).

Percentage Reduction = 12/50 = 0.24

0.24 In percentage is 0.24 * 100 = 24%

D is the correct answer.
