Answer:
The ratio is 1 : 2 1/4
Step-by-step explanation:
The ratio would be 1 : 2 1/4 because if you look at the difference between batch 1 and 2, it has a difference of 1 in the amount of sugar, and 2 1/4 difference in the amount of flour. Compare it to batch 3, same thing. 2+1 is 3, and 4 1/2 = 4 2/4, and adding 2 1/4 would give you 6 3/4. This would make the ratio 3 : 6 3/4, but since it is the unit rate of change, the change ratio would be 1 : 2 1/4.
The unit rate of change of flour with respect to sugar will be 2.25.
Let the thing that is changing be y and the thing with which the rate is being compared is x, then we have the average rate of change of y as x changes as:
Average rate = (y₂ - y₁) / (x₂ - x₁)
Melissa made three batches of oatmeal cookies.
Her recipe calls for amounts of sugar (in cups) and flour (in cups) in the following ratios.
Then the unit rate of change of flour with respect to sugar will be
Unit rate = (9 - 6.75) / (4 - 3)
Unit rate = 2.25
