<human>:  Marlon has a gift card for $200. He spent half of it on Monday and one-fourth of the remainder on Tuesday. How much was left on his gift card?
<bot>: How much was left on Monday? ** Since Marlon spent half of the gift card, then half of it which is $200/2 = $<<200/2=100>>100 remained on Monday.
How much was spent on Tuesday? ** Then on Tuesday, he spent $100/4 = $<<100/4=25>>25.
How much was left on his gift card? ** Therefore, he has $100 - $25 = $<<100-25=75>>75 left in his gift card.
