If Maria decides to purchase the sun hat (for $8.00) and the beach towel (for $7.00), the total cost of her purchase would be $15.00. Since she is spending her entire available budget of $20.00 on these items, the opportunity cost would be what she has to give up to make that purchase.
The items Maria would be giving up are:
- The magazines (which cost $8.00)
- The bathing suit (which costs $15.00)
So, the opportunity cost of purchasing the sun hat and beach towel includes:
- The magazines
- The bathing suit
Thus, the correct responses would be:
- the magazines
- the bathing suit
