ANSWER
B) 299 sections with 19 feet left over
EXPLANATION
To find the number of sections we have to divide the length of the rope by the length of each section:
[tex]\frac{6298}{21}=299.9047619[/tex]
The whole part of this result is the number of 21-foot sections we'll have. If we multiply the decimal part by 21 we can find the length of the rope left:
[tex]0.9047619\times21=19[/tex]
We have 19 feet left of the rope after cutting 299 21-foot long sections
