Sewing patterns recommend buying extra fabric in case of mistakes. Jessica bought 5 yards of fabric, plus 20% extra fabric. Derek bought 3 yards of fabric, plus 25% extra. Who bought more fabric? How much more?

Answers

Answer:

Jessica bought 2.25 yards more material than Derek.

Step-by-step explanation:

Jessica bought 5 yards of fabric.

20% extra fabric = 20% of 5

                            = (20×5)/100

                            = 1 yard

Total fabric bought by Jessica = 5+1 = 6 yards

Derek bought 3 yards of fabric.

20% extra fabric = 25% of

                            = (25×3)/100

                            = 0.75 yard

Total fabric bought by Derek = 3 + 0.75 = 3.75 yards

So,

Difference = 6 - 3.75 = 2.25 yards

Answer: Jessica bought 2.25 yards more material than Derek.

20% = 0.2
(5 * 0.2) + 5
5 * 0.2 = 1
5 + 1 = 6

25% = 0.25
(3 * 0.25) + 3
3 * 0.25 = 0.75
3 + 0.75 = 3.75

6 - 3.75 = 2.25

Jessica bought 2.25 yards more material than Derek.
