Answer:
The smaller percent change of push-ups is on Monday with 50%
Step-by-step explanation:
On Monday, the change in pushups is:
(30 - 20)/20 = 10/20 = 1/2
This represents (1/2) * 100 = 50 percent
On Friday, the change in pushups is:
(40 - 25)/25 = 15/25 = 3/5
This represents (3/5) * 100 = 60 percent
Monday is 50%
Friday is 60%
Therefore, the smaller percent change occured on Monday, with 50 percent
