Question
Kelly and her mom want to make matching pairs of polka-dotted pajama pants. So, they go to the craft store to pick out fabric. Kelly 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?
Solution
First, we need to convert the yards of fabric they bought into feet. We know that 1 yard is equal to 3 feet. So, 4 yards of fabric is equal to 4 * 3 = 12 feet of fabric.
Next, we need to subtract the amount of fabric they need for their pajamas from the total amount of fabric they bought. Kelly needs 4 feet of fabric and her mom needs 6 feet of fabric, so together they need 4 + 6 = 10 feet of fabric.
Finally, we subtract the amount of fabric they need from the total amount of fabric they bought to find out how much fabric will be left over. So, 12 - 10 = 2 feet of fabric will be left over.
