Verified step by step guidance1
Identify the price index values for the two years given: 2018 has a price index of 110, and 2019 has a price index of 115.
Understand that the change in the price index is found by subtracting the earlier year's index from the later year's index.
Set up the calculation for the change: \(\text{Change} = \text{Price Index}_{2019} - \text{Price Index}_{2018}\).
Substitute the values into the formula: \(\text{Change} = 115 - 110\).
Interpret the result as the number of points the lunch price index increased or decreased from 2018 to 2019.
