Question

Bernie helped design a magician costume for a school play. He used 5.75 feet of ribbon for the magician's wand. He used 11.75 feet of the same ribbon to decorate the magician's robe. If Bernie used $10.50 of ribbon in all, how much did the ribbon cost per foot?

Answer 1

Answer:

The ribbon cost per foot $0.6 per foot

Step-by-step explanation:

Total number of ribbon used = (5.75 + 11.75) = 17.50 feet

17.50 feet of ribbon cost = $10.50

1 foot of ribbon cost = x

Cross Multiply

17.50 × x = 1 foot × $10.50

x = 1 foot × 10.50/17.50

x = $0.6

The ribbon cost per foot $0.6 per foot

Answer 2

Answer: $0.75

Step-by-step explanation:

Total amount used for the ribbons = $1.50

Total feet of ribbons used = 5.75 feet + 11.75 feet = 17.5 feet

The cost of ribbon per foot will now be:

= $10.50/17.5

= $0.6 per foot
