Difference between the number of paper balls that Wendy and Lynn folded in the end is repeated.
Difference between the number of paper balls that Wendy and Lynn folded in the end
= 7 p - 3 p
= 4 p
Difference between the number of paper balls that Wendy and Lynn folded in the end
= (1 u + 70) - (1 u + 22)
= 1 u + 70 - 1 u - 22
= 70 - 22
= 48
4 p = 48
1 p = 48 ÷ 4 = 12
Number of paper balls that Wendy folded
= 7 p
= 7 x 12
= 84
Answer(s): 84
