A)
The formula for direct variation is written as Y = KX, where k is the direct variation you need to solve for.
Y is the total amount raised and X would be the number of attendees:
100 = K5
Divide both sides by 5:
K = 100/5
K = 20
B. The constant of variation is K which is 20
C) Using the formula from A: y = kx, replace k with 20 and x with 60 and solve for y:
y = 20 * 60
y = 1200
The total is: $1,200
2. A relationship is proportional when the ratio is a constant number.The relationship is non proportional when the ratio varies between the different values.
Let's see -
Let's solve the first question step-by-step
(WARNING - This may confuse you a little)
1)
4 1/8 + 2 1/3
= 33/8 + 2 1/3
= 33/8 + 7/3
= 155/24
= 6 11/24 --------> Note that this is your final answer and it already looks simplified down to its simplest form. :)

2) This equation, as far as solving it, is no different than number 1. Let's go for it!
5 17/18 - 2 2/3
= 107/18 - 2 2/3
= 107/18 - 8/3
= 59/18
= 3 5/18 -----------------> This is your final answer, and, as before, it looks simplified enough.

Answer:
781/1680
Step-by-step explanation:
Don't you have a calculator?
I assume that by (1 2/3 1/9), you mean (1+2/3)*(1/9)
Assuming that you put all necessary parentheses:
781/1680, approx. 0.4648809523809524
