Using a system of equations, it is found that 124 children and 113 adults attended the dude ranch.
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given as follows:
The Big House on the Range dude ranch had 237 customers, hence:
x + y = 237 -> x = 237 - y.
The children's rate is $53.50 and the adult's rate is $107.00. The total collected this last weekend was $18,725.00, hence:
53.5x + 107y = 18725.
Since x = 237 - y:
53.5(237 - y) + 107y = 18725
53.5y = 6045.5
y = 6045.5/53.5
y = 113 adults.
x = 237 - y = 237 - 113 = 124 children.
