Which number line represents the solution to the inequality (will make brainliest) pls help

C

Step-by-step explanation:

because the solution dors not include -3 but everything less than.

The annual snowfall in 78th year is 29.88 inches

Step-by-step explanation:

* Lets explain how to solve the problem

- The decrease in the annual snowfall has been on average 0.24 inches

  per year

- x represents the number of years since 1920

- y represent the annual snowfall

- The initial measurement in 1920 was 48.6 inches

- We need to find the annual snowfall in the 78th year after records

  were kept

- The form of the linear function is y = mx + c, where m is the slope

  of the line and c is the y-intercept

- The slope means the average change in y for the change of  x

∴ The slope is the average decreases of the snowfall

- Decreases means negative value of slope

∴ m = -0.24

- The y-intercept means the value of y at x = 0

∴ The initial amount is the y-intercept

∴ c = 48.6

∴ The linear function is:

  y = -0.24 x + 48.6

∵ y = -0.24 x + 48.6

∵ x = 78

- Substitute the value of x in the function

∴ y = -0.24(78) + 48.6

∴ y = -18.72 + 48.6

∴ y = 29.88 inches

* The annual snowfall in 78th year is 29.88 inches
