Colette and her mom want to make matching pairs of polka-dotted pajama pants. So, they go to the craft store to pick out fabric. Colette needs 4 feet of fabric for her pajamas, and her mom needs 6 feet of fabric. But, the store only sells fabric by the yard. If they buy 4 yards of fabric, how many feet will be left over?
Since they buy 4 yards of fabric, they have 4 x 3 = 12 feet of fabric.
Colette needs 4 feet, so that leaves 12 - 4 = 8 feet.
Her mom needs 6 feet, so that leaves 8 - 6 = 2 feet.
Therefore, there will be 2 feet of fabric left over.
