Answer:

The answer is below

Step-by-step explanation:

Let the number of bottles be y and the number of minutes the machine operate be x.

Given that number of bottles be is proportional to the number of minutes the machine operate, hence:

y is proportional to x.

⇒ y α x

y = kx, where k is a constant

when the number of bottles (y) = 250, the time the machine operates (x) = 20 minute. Therefore:

y = kx

250 = 20k

k = 250/20

k = 12.5

Hence the relationship between x and y is given as:

y = 12.5x

Plotting the function y = 12.5x using geogebra
