Question:
Jordyn, Teri, and Morgan are going to have a kite-flying contest. Jordyn and Teri each have one roll of kite string. They also each have 45 yards of extra string. Morgan has three rolls of kite string plus 10 yards of extra string. All the rolls of string are the same length. The girls want to see who can fly their kite the highest.
Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together, so their kite can fly higher. Write at least two expressions to show how much kite string Jordyn and Teri have. Let x represent the number of yards of string on one roll.

<u></u>
<u></u>
<u>Morgan</u>
<u></u>
<u></u>

Required
Expression for Jordyn and Morgan
Let the total kite by Jordyn and Teri be represented with y
This is calculated as:

This gives:

1 roll is represented with x.
So:


This can be rewritten as:

we know that

in this problem



Step 
Find the total employee benefits
Let
EC------> total employment compensation
EB--------> total employee benefits
GP------> gross pay
JE------> job expenses


Step 
Find the percentage of the total employee benefits
we know that
total employee benefits is equal to 
gross pay is equal to 
by proportion

%
therefore
the answer is the option
