A mini golf course charges different prices for adults and children. On Saturday, 50 adults and 50 children played, and the golf course earned $800. On Sunday, 65 adults and 75 children played, and the golf course earned $1,100. How much does the golf course charge for adults!

Let the cost for an adult be x and the cost for a child be y.

From the given information, we can create a system of equations:

50x + 50y = $800
65x + 75y = $1,100

Solving this system of equations, we find:
x = $10
y = $6

Therefore, the mini golf course charges $10 for adults.
