Can someone justify my answer for me -

Step-by-step explanation:

You are correct in what you are doing. All you need do is show that what you got can be expressed algebraically.

Let x be the time in hours.

Let y be the snowfall in inches.

The first one does not work.

y = k * x

12 = k * 6                     Divide both sides by 6

12/6 = k/6

k = 2

All the rest will fit into this equation.

try x = 2.5

y = k * x

y = 2 * 2.5

y = 5           which is just the amount of snowfall you should get.

0 < x ≤ 200 and 0 < y ≤ 400
