Answer:
- I cannot see number 4
Step-by-step explanation:
r
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.
Answer:
No, he is not correct because the constant in his answer should have been 21 not 7.
Step-by-step explanation:
Therefore, the correct answer is the fourth; he should have put 21.

➷ The range is the highest value minus the smallest value
Therefore, you just need to subtract the two values to find the values:
-2 - 4 = -6
The difference is just 6, so your answer is C. 6
