wednesday?

Step-by-step explanation:

A) The pants are $45.

On Monday, everything is 15% off

100 - 15 = 85, so Jack will pay 85% of the original price.

45 * 0.85 = $38.25

B} On Friday, everything is 50% off

100 - 50 = 50, so Jack will pay 50% of the original price.

45 * 0.5 = $22.50

38.25 - 22.50 = 15.75

Jack would have saved $15.75

C) Blouse: $32, Skirt: $46, Sweater: $55. On Wednesday, everything is 25% off.

100 - 25 = 75

32 + 46 + 55 = 133

133 * 0.25 = 33.25

Susan has a $33.25 discount.

D) 133 - 33.25 = 99.75

Susan paid $99.75

E) 133 * 0.5 = 66.5

99.75 - 66.5 = 33.25

Susan would have saved $33.25
