Explanation:
the admission ticket was $27, so, in order to get the amount of money for food and beverages we need to subtract the ticket price from the total price :
43 - 27 = $16
so he spent $16 on items at the conception stand.
each item costs $4. to find the number of items we need to see how often the price of one item fits into the total amount. that is the typical use of a division.
so, he bought
16/4 = 4 items
the fan bought 4 items at the concession stand.
