Salwa went to the mall to buy supplies for her math project. She spent half of what she had plus $2.00 in the first store; half of what she had left plus $1.00 in the second store; half of what she had left plus $1.00 in the third store; and in the last store, half of all she had. Three dollars were left over. How much money did she start with?

She began with $64.00
I'm sure I went about this the hard way, but...
Ending amount = 3
3 = 1/2(x)
x = 6 (before last store)
6 = 1/2x + 1
x = 14 (before 3rd store)
14 = 1/2x + 1
x = 30 (before 2nd store)
30 = 1/2x + 2
64 = x (before 1st store ie when she began)
