Explain why a relative price is an opportunity cost. The money price of a pound of bananas is $0. 90 and the money price of a tu
dimaraw [331]

The opportunity cost is stated in relative pricing, that is, the price of one option in comparison to another.

When there are numerous vendors in a market but no one is significant enough to control the price of a product. Because both items must be produced, the relative price must match the opportunity cost. If the opportunity cost of one good is lower in the home country than so will be the relative price.

As bananas cost $0.90 per kg, so, if  a toothpaste is  for $2.25, we are forgoing 2.25 kgs banana (2.25/0.9). Thus, the opportunity cost is 2.5 kg bananas which is equal to the relative price of bananas.

Therefore, relative price is an opportunity cost.
