Tiffany and Gabby had the
same number of mochi balls at first. Tiffany gave 28 mochi balls away to her sister. In the end, Gabby had five times as many mochi balls as Tiffany. How many mochi balls did Tiffany have at first?

| After |
1 u |
5 u |
The number of mochi balls that Gabby had remains unchanged.
Number of mochi balls that Tiffany gave away
= 5 u - 1 u
= 4 u
4 u = 28
1 u = 28 ÷ 4 = 7
Number of mochi balls that Tiffany had at first
= 5 u
= 5 x 7
= 35
Answer(s): 35
