Answer:
b. increases to $57 and the quantity of goose-down pillows purchased in Honduras decreases.
Step-by-step explanation:
A tarrif is defined as the tax that government places on goods that are imported into a country.
The effect on imports is to increase the price of the goods .
If Honduras imposes a tarrif of $7 on pillows the new price will be 50 + 7= $57
As price increases according to the law of demand, there will be a fall in demand of pillows. Customers will look for cheaper alternatives.
