ANSWER
B) 299 sections with 19 feet left over
Step-by-step explanation
To find the number of sections we have to divide the length of the rope by the length of each section:
![(6298)/(21)=299.9047619](https://img.qammunity.org/2023/formulas/mathematics/college/wk0gf6g9f7uesyj47v9ucmuyxb5l7sn8uf.png)
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:
![0.9047619*21=19](https://img.qammunity.org/2023/formulas/mathematics/college/ib03wac8h8xd5woa69uanoz0dusys4x1xk.png)
We have 19 feet left of the rope after cutting 299 21-foot long sections
