A golf course charges different prices for adults and children on Saturday 50 adults and 50 children played and the golf course earned 800.00 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 X be the price for adults and Y be the price for children.

Forming equations based on the given information:

50X + 50Y = 800 (Equation 1)
65X + 75Y = 1,100 (Equation 2)

Multiply Equation 1 by 65 and Equation 2 by -50:

(65)(50X + 50Y) = 65(800)
(50)(65X + 75Y) = -50(1,100)

Solving the above equations will give:
3250X + 3250Y = 52,000
-2500X - 3750Y = -55,000

Adding both equations:

750X = -3,000
X = $4

Therefore, the golf course charges $4 for adults.
