Answer:
D
Step-by-step explanation:
Let cost of member be "m" and cost of non-member be "n".
We know:
3 member and 4 non-member pay $79.
So we can say:
Also, from the problem, we know that:
non-member fee is 11 more than member fee
Thus, we can write:
n = 11 + m
Putting this in 1st equation, we can solve for "m":
Members have to pay $5, so non-members will pay "11" more, that will be:
Non-Members = 11 + 5 = 16
<u>$16, D is the correct answer</u>
This is equal to:
When you add a negative number, it turns into subtraction.
First, I would change it to mixed numbers:
Now, you need to change the denominators to make sure they are the same on both fractions. I changed the first fraction's denominator to 4 so they match. You can do this by multiplying the numerator by 2:
Now, you simply subtract:
10-9=1
1/4 is your answer.
I hope this helps :)
