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.
Answer:


Step-by-step explanation:
From the complete question, we have:
<u>Jordyn & Teri</u>
<u></u>
<u></u>
<u></u>
<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:

To get an average score of 80% (out of four exams), a total of 4*80%=320% is needed, so the minimum required for the 4th test is 320-(75+97+60)=88.
To get an average score of 89% (out of four exams), a total of 4*89%=356% is needed, so the maximum required for the 4th test is 356-(75+97+60)=124, which is impossible.
So the next exam grade must range between 88 and 100 to get a grade b in the class.
