Agatha has some money to spend on a new bike. She spends $15 on the frame, and $25 on the front wheel. If she has $20 left to spend on a seat and handlebar tape, how much money, in dollars, did she have at first?
Agatha spends 15+25=<<15+25=40>>40 dollars.
Agatha had 40+20=<<40+20=60>>60 dollars at first.
#### 60
