We have to evaluate the unit rate for 1 Apple for $0.19.
The formula for unit rate is shown below.
[tex]\text{Unit rate }= \frac{\text{Cost of the prodcut}}{\text{Number of units}}[/tex]
Now, we have been given the cost of the apple is $0.19 and the number of unit is 1. Hence, using the above mentioned formula, the unit rate is given by
[tex]\text{Unit rate }= \frac{0.19}{1}\\ \\ \text{Unit rate }= 0.19[/tex]
Therefore, the unit rate is 0.19 dollars per apple.
