Lizzy: Marian's pending credit card balance is $126.00. She puts $60.00 worth of groceries on her card and half that amount in gas. She returned some bath towels for $45.00. What's the new balance on her credit card?.
Me: Hmmm, let me think. I think this is the detailed solution:

Her gas is half the price as her $60.00 groceries so that's 60 / 2 = $30.00 in gas. Her card has a balance of $126.00 and she added $60.00 in groceries and $30.00 in gas for a total of 126 + 60 + 30 = $216.00. Her balance is $216.00 and she returns $45.00 worth of merchandise for a new balance of 216 - 45 = $171.00. Final answer: 171.
