Final answer:
The total amount collected for daily fees, factoring in both adults and children, would be calculated by the expression 10a + 5c, where 'a' and 'c' are the number of adults and children respectively.
Step-by-step explanation:
To calculate the total amount collected in daily fees at Fun Town amusement park for a adults and c children, we will use the given price per adult ($10) and per child ($5). If there are a adults, the total cost for all adults would be 10 times a, which is represented by 10a. Similarly, for c children, the cost would be 5 times c, which is 5c. Adding these two amounts together gives us the total collected from both adults and children for daily fees.
The correct expression is therefore:
10a + 5c
This means for every adult, $10 is added to the total, and for every child, $5 is added. The total amount collected is the sum of these two amounts.
