None of the options shows an alternative Tina has, a real alternative would be a credit card and cash ($190)
In economics, an alternative is an element that replaces or substitutes another. For an element to be considered an alternative it needs:
- To belong to the same category or have the same function.
- To be possible for the user to replace the first element using the alternative.
Based on this, let's analyze each of the options:
- Jacket and $100: These are not alternatives because Tina wants a jacket and this product cannot be replaced with money as money will not protect Tina from cold weather.
- Shoes and a jacket: These are not alternatives because Tina wants the two products not only one.
- Credit card and $100: These would be alternatives if the total cost was $100. However, using a credit card Tina can pay for both products but using $100 she can only pay for one of the products.
Therefore, the options do not present alternatives; but one valid alternative is a credit card and $190.
