Worked Solution
Step 1: After the transfer, let Mei Ling have M dollars; Stan has 3M. Total is unchanged at $26.80, so M + 3M = 26.80 → 4M = 26.80 → M = $6.70.
Step 2: After the transfer: Mei Ling = $6.70, Stan = 3 × $6.70 = $20.10.
Step 3: Before the transfer, Mei Ling had $4.50 MORE than after (because she gave $4.50 away): Mei Ling at first = $6.70 + $4.50 = $11.20.
Answer: $11.20
Correct answer: $11.20
