conversations.value: Can you break down the solution for me for this math problem: Inez has $150. She spends one-half on hockey skates and a certain amount on hockey pads. If Inez has $25 remaining, how much did the hockey pads cost, together, in dollars?

conversations.value: She spent 150/2=$75 on hockey skates.
  Let X be the amount Inez spent on hockey pads.
  150-75-X=25
  75-X=25
  X=50
  The hockey pads cost $50.
