Explanation:
The computation is shown below:
Relative price of a carton of juice = Cost of carton of juice ÷ Cost of can of soda
= $1.75 ÷ $1.25
= 1.4
And, the relative price of a carton of juice if the absolute price of a carton of juice is unchanged
Relative price of a carton of juice = Cost of carton of juice ÷ Cost of can of soda
= $1.75 ÷ $1.50
= 1.167
Therefore, the relative price is decreased
