Answer 1

A.Take 25% off first, then take $20 off.

Step-by-step explanation:

To determine the situation that leads to a lower price, we assume the price of the purchase is $50 and calculate for each of the scenarios.

Case A

25% off of $50 = 0.75 x 50 = $37.50

If we then take $20 off, we have: $37.50 - 20 =$17.50

Case B

If we take $20 off, we have: $50-20 = $30

Next, 25% off of $30 = 0.75 x 30 =$22.5

Therefore, Case A will lead to a lower price.
