The problem above uses the concept of ratio and proportion. The ratio between the cost and amount of the organic milk should always be equal. The proportion between two cases is shown below,
($2.52 / 0.5 gallon) = (x / 4 gallons)
Solving for x gives x = 20.16. Therefore, 4 gallons of organic milk costs $20.16.
So r is a number that when you add to t it will increase so its
T + r
9 divided by 83 = .1084. .1084 is the quotient.
If you are talking about a graph:
The input would be the number of adult tickets.
The output would be the amount of money.
If you talking about it normally:
The input would be the amount of money.
The output would be the number of adult tickets.
