for an art project. The cost of the ribbon is 5 feet for $3.00.

Feet of Ribbon 1 5 10 15

a. Complete this ratio chart based on the information provided.

b. How many feet of ribbon can Serena buy for $12.00?

c. If Serena needs 17 feet of ribbon, how much will she pay? How do you know?

Answer 1

(can't answer a since the ratio chart is incomprehensible through text)

b. 20 feet of ribbon for $12.00

12 / 3 = 4

5 x 4 = 20

c. 17 feet of ribbon for $10.20

find unit rate (cost / quantity)

3 / 5 = $0.60 per feet

0.60 x 17 = 10.2
