Hailey received some cash for birthday. She spent $14.48 on a CD and donated $25.00 to charity. She put half of what was left in

DaniilM [7]

Work backwards.

After she put half of what she had left in, she had 17.76.

Multiply by 2:

17.76 * 2 = 35.52

Add 25:

35.52 + 25 = 60.52

Add 14.48:

75

So she received $75 on her birthday.
