miniature 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 A be the price for adults and C be the price for children in dollars.
On Saturday, the golf course earned 50A + 50C = $800.
On Sunday, the golf course earned 65A + 75C = $1,100.
We can rewrite the first equation as A + C = $16 and the second equation as 13A + 15C = $220.
Multiplying the first equation by 13, we get: 13A + 13C = $208.
Subtracting the second equation from the first equation, we get: 13C - 15C = $208 - $220.
Combining like terms, we get: -2C = -$12.
Dividing both sides by -2, we get: C = $6.
Substituting the value of C in the first equation, we get: A + $6 = $16.
Subtracting $6 from both sides, we get: A = $16 - $6 = $10.
The golf course charges $10 for adults. Answer: \boxed{10}.
