A miniature golf course charge different prices for adults and children on Saturday 50 adults and 50 children played Andy Golf Course earned $800 on Sunday 65 adults in 75 children play and the golf course earned $1,100. How much does a golf course charge for adults?

The golf course charge $10 for adults

Step-by-step explanation:

Let x represent the amount that the golf course charge for adults.

Let y represent the amount that the golf course charge for children.

On Saturday, 50 adults and 50 children played and Andy Golf Course earned $800.

This means that

50x + 50y = 800 - - - - - - - - - - - -1

On Sunday, 65 adults in 75 children play and the golf course earned $1,100. This means that

65x + 75y = 1100 - - - - - - - - - - 2

Multiplying equation 1 by 65 and equation 2 by 50, it becomes

3250x + 3250y = 52000

3250x + 3750y = 55000

Subtracting, it becomes

- 500y = - 3000

y = - 3000/ - 500

y = 6

Substituting y = 6 into equation 1, it becomes

50x + 50 × 6 = 800

50x + 300 = 800

50x = 800 - 300 = 500

x = 500/50

x = 10

i believe that the answer is

b. y-1=-2(x-4)

hope this !
