Question

A pair of grant high school hockey fans counted the number of games won by the school each year

what was the rate of change between 2014 and 2015​

Answer 1

The rate of change in the number of games won by the school's hockey team between 2014 and 2015 is found by subtracting the number of games won in 2014 from those in 2015 and dividing by 1 year.

The question is asking to calculate the rate of change in the number of games won by the school's hockey team between 2014 and 2015. The rate of change can be found by subtracting the number of games won in 2014 from the number of games won in 2015 and dividing by the time period between the two, which in this case is 1 year.

Here is the step-by-step explanation:

1. Find the number of games won in 2014.
2. Find the number of games won in 2015.
3. Subtract the number of games won in 2014 from the number of games won in 2015.
4. Divide the result by the time period between the two years (2015 - 2014), which is 1 year.

Let W2015 be the number of games won in 2015 and W2014 be the number of games won in 2014. The rate of change is then calculated as (W2015 - W2014) / 1.

Answer 2

8

Explanation:

2015: 9 games won

2014: 1 game won

rate of change = 2015 games won - 2014 games won

rate of change = 9 - 1

rate of change = 8
