Question 3

Table given below shows the Consumer Price Index (CPI) for selected years. The mathematical model for the data given below is $y = - 0.031 t ^ { 2 } + 5.887 t + 24.429$ , where $y$ represents the CPI and $t$ represents the year, with $t = 5$ corresponding to 1975 . Use the model to predict the CPI for the year 2010. Round your answer to the nearest integer.
