Question

Sewing patterns recommend buying extra fabric in case of mistakes. Jessica bought 6 yards of fabric, plus 15% extra fabric.

Derek bought 5 yards of fabric, plus 30% extra. Who bought more fabric? How much more?

Answer 1

Jessica bought more fabric

Explanation:

15% of 6 is 0.9 and 30% of 5 is 1.5 so 6+0.9 = 6.9 and 5+1.5 = 6.5 so Jessica bought 0.4 yards more than Derek.
