Final answer:
To write an equation representing the amount of snow that has fallen after x hours, use the form y = rx, where r is the rate of snowfall per hour, and y is total snowfall. If the rate is 2 inches per hour, the equation would be y = 2x.
Step-by-step explanation:
The question seems to imply the need for an equation that relates the amount of snowfall to the amount of time it has been snowing. Since there isn't a specific rate provided directly in the question, we have to look at the provided context. We can see references to other rate equations, such as y = 55x + 75 and y = 1350 - 1.2x, which describe other situations such as labor charges and lawn mowing. However, for the snowfall, we will assume the rate of snowfall is constant and use a similar format. Thus, the equation will be written as y = rx, where r represents the rate of snowfall per hour and y is the amount of snow that has fallen after x hours.
If we are provided with the rate of snowfall, we could replace r with that number to complete the equation. For example, if the rate was 2 inches of snow per hour, the equation would be y = 2x. This format allows for the calculation of snow depth based on any given time interval.
