Amy and Bell had $26 altogether at first. After spending $4, Amy received $5 from Bell. They have the same amount of money now.
How much did Amy have at first ?
my ans is
26 divided by 2 = 13
13 + 4  5 = 12
model answer is 26  4 = 22
22 divide by 2 = 11
11 + 4  5 = 10
Can u help to explain if u agree with the model answer.
Thank you.

Since we do not know Amy and Bell's sharings, we will have to minus the amt spent by Amy from the total, that's
26  4 = 22
Now they have equal share, therefore
22/2 = 11
Amy has 11 only when Bell gave her 5, therefore
115 = 6
To get what Amy had at first, you have to add back what she had spent, that's is
6 + 4 =10
Hope this is clear.
