Answer:
3,290 inches of Ribbon
Step-by-step explanation:
Assuming that Sarah needs a total of 1,000 Ribbons we would simply need to multiply this total amount by the size of each individual Ribbon, which according to Sarah is 3.29 inches. This is because this would be like adding the size of each individual ribbon to get the total length. Like so...
1,000 * 3.29 = 3,290inches
Therefore, Sarah would need a total of 3,290 inches or
3,290 / 12 = 274.16ft of ribbon
