Answer:
The difference in prices is $0.29.
Explanation:
Given:
Ten years ago ago, you could buy a loaf of bread for $1.21. Twenty years ago, you could buy a loaf of bread for $0.92.
Now, to find the difference in prices.
Cost price of loaf of bread 10 years ago = $1.21.
Cost price of loaf of bread 20 years ago = $0.92.
Now, to get the difference in prices we subtract the cost price of loaf of bread 20 years ago from the cost price of loaf of bread 10 years ago:
Therefore, the difference in prices is $0.29.
