To determine the opportunity cost of Maria's purchase, we first need to know how much she plans to spend on the sun hat and beach towel.
The sun hat costs $8.00, and the beach towel costs $7.00, so together they cost:
$8.00 + $7.00 = $15.00
Since Maria has $20.00, after buying the sun hat and the beach towel, she would have:
$20.00 - $15.00 = $5.00 remaining.
Now, she will not be able to purchase something else with that money. The options she is giving up for the $15.00 spent on the sun hat and towel are:
- The magazines for $8.00
- The bathing suit for $15.00
Since she cannot buy both the magazines and the bathing suit, the opportunity cost of her purchasing the sun hat and towel is the value of the items she cannot buy with that $15.00.
Thus, the opportunity cost includes:
- The magazines
- The bathing suit
So the correct responses are:
- the magazines
- the bathing suit
