What I understand from the question is :
Class brought cans of fruit = six
Cans of beans = four
Boxes of noodles = seven
Cans of Soup = four
Ratio of cans of fruit to the total number of food items = ?
Total number of food items = 6 + 4 + 7 + 4 = 21
Cans of fruits : Total number of food items
6 : 21 = 2 : 7
So the ratio of cans of fruit to the total number of food
items is 2 : 7
It means two out of every seven food items the class brought is can of
fruits.
Cross multiplying making x subject of the equation or multiplying 42 from both sides
Answer:

The actual solution to the system lies in quadrant 1
You can even test points in that double shaded region
check : (6,2)
Im guessing you meant whats the average of 3,4,5, and 8. which would be 5.
Add 3,4,5, and 8 and then divide by how many number you added up which would be 4.

Answer: $111.11</h3>
=======================================================
Explanation:
Let's say you earn x dollars.
You pay 10% tax on that, which means you pay 0.10x dollars.
This would drop to x-0.10x = 0.90x which is the amount earned after tax.
So you pay 10% of what you earn, and keep 90% of the rest.
Set this equal to the target $100 you want and solve for x.
0.90x = 100
x = 100/0.90
x = 111.11
Notice that 10% of this is 0.10*x = 0.10*111.11 = 1.11 when rounding to the nearest penny. So you'll pay $1.11 in tax. Therefore, you'd have x-0.10x = 111.11 - 1.11 = 100 left over. So the answer checks out.
