Answer:
It cannot be determined if they are worse off
Explanation:
In this question, we are asked to determine if consumers today are worse off then consumers in the year 1975.
From the data gathered in the question, it is not likely to know if consumers today are worse off or better than consumers in 1975.
This is because, with this data, only the inflation rate can be measured. Now what determines if the consumer now is better off or worse off?
If the consumer’s income increase at a rate greater than the pace at which inflation is increasing, then obviously he would be better off now than before.
If the pace of increase is the same, then he is neither better off nor worse off.
Lastly, if the income has increased at a rate which is lesser than the inflation pace, then we can say that the consumer today is worse off
