Question

The table shows the proportional relationship between the price for a certain number of buckets of golf balls at a driving range.

Buckets 3 5 7
Price (dollars) 25.50 42.50 59.50


Determine the constant of proportionality.
25.5
17
9.5
8.5

Answer 1

Answer: 17 is the Constant

Explanation:
Buckets: 3 5 7

Price (dollars):25.50 42.50 59.50
If you were to do
25.50-42.50 you would get 17
42.50-59.50 you also would get 17
You dont actually need to do the formula, if the answer IS proportional, then you can just do the first number minus the second, and the second minus the third.
There is also the formula that you can use to get the answer, which the other person did.
( Constant of Proportionality )

What is Constant of Proportionality?
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

Answer 2

Explanation:

25.50+17=42.50

42.50+17=59.50

so the numbers are constantly going up by 17 if you add the .50 you will change the number by 1 unit
