8 is A
9 is D
10 is C
11 is B
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:
$40.12.
Step-by-step explanation:
We have been given that your family went to a pancake house for breakfast and spent $34 your family decides to leave at 18% tip how much is the tip. We are asked to find the total amount of bill with the tip.
The total amount of bill with the tip will be cost of breakfast plus 18% of cost of breakfast.




Therefore, the total amount of the bill will the tip would be $40.12.
