Step 1
Add the length of the 2 ropes of Jen.
[tex]\begin{gathered} 13\frac{1}{8}+21\frac{3}{4} \\ \frac{105}{8}+\frac{87}{4}=\frac{279}{8}ft \end{gathered}[/tex]Step 2
Find the difference between the rope of Jen (279/8)ft and Kelsey(71/2)ft
[tex]\begin{gathered} 35\frac{1}{2}-\frac{279}{8} \\ =\frac{71}{2}-\frac{279}{8} \\ =\frac{5}{8} \\ \\ \end{gathered}[/tex]Hence, Kelsey has 5/8 feet of more rope. Option C
