Question

The admission fee at a small rodeo is $8.50 for children and $15.00 for adults. On a certain day, 400 people enter the rodeo and $4,862.50 is collected. Which system of equations can be used to determine how many children, c, and how many adults, a, attended the rodeo?

Answer 1

adults = a

children = c

therefore

`\begin{gathered} a+c=400 \\ 15a+8.5c=4862.5 \end{gathered}`
