Answer: Let's call the number of adults admitted "A" and the number of children admitted "C". We know that:
A + C = 4900 (total number of people admitted)
And the total revenue is:
2.75A + 0.25C = $6,962.50
We can use the first equation to solve for one of the variables in terms of the other:
C = 4900 - A
Substitute this expression for C into the second equation:
2.75A + 0.25(4900 - A) = $6,962.50
Expand and simplify the right side:
2.75A + 1225 - 0.25A = $6,962.50
2.5A = 5737.5
Solve for A:
A = 2298
So there were 2298 adults and 4900 - 2298 = 2602 children admitted.
