Answer: 115 meters

Explanation:

From the question, we are informed that Phoebe knit a hat for a friend and that she started with 197 meters of yarn but when she finished, she had 8,200 centimeters of yarn left over.

First, we have to understand that 100 centimeters equals 1 metre. Therefore, 8200 centimeters of yarn is the same as 8200/100 = 82 meters of yarn.

The yarn that Phoebe use to knit the hat will be:

= 197 meters - 82 meters

= 115 meters
