From the given table, it can be seen that
The cost of 3 yards of fabric = $5.25
Then the cost of 1 yard of fabric =
Now, If the price is the same for each yard then the cost of 12 yards of fabric =
⇒ The cost of 12 yards of fabric = $21

The average rate of change = 1.59 ≈ 2
The average rate of change can be calculated by
1) The first one = = 1.5
2 ) the second can also be solved by ; 8 + 2/ 2 = 5
3 ) the third one will be 20 + 6 / 2 = 13
4) 8.5
5) 12.5
To calculate the average rate of change
we will first add all the distance
Adding all the distance we will get the sum = 3 + 8 + 20 + 10 + 10 = 51
The total time = 2 + 6 + 9 +15 = 32
Thus the average rate of change = 51 / 32 = 1.59
