Total number of erasers that Min and Tammy shared = 100%
If Min gave 245 erasers to Tammy, both would have the same number of erasers.
Number of erasers that each would have in the end
= 100% ÷ 2
= 50%
Number of erasers that Min gave to Tammy
= 85% - 50%
= 35%
35% → 245
1% → 245 ÷ 35 = 7
Number of erasers that Min had
= 85%
= 85 x 7
= 595
Answer(s): 595
