The admission fee at a zoo is $2 for children and $4 for adults. if 1800 people enter the zoo and $6000 is collected, how many adults went to the zoo? a) 300 b) 600 c) 1200 d) 1500

C) 1200

Step-by-step explanation:

x= adult, y = kid

x+y=1800

4x+2y=6000

x=1800-y now put that into the 2nd equation

4(1800-y)+2y=6000

7200-4y+2y=6000

4y-2y=7200-6000

2y=1200

y=600

x=1800-600 = 1200

 so 1200 adults and 600 kids

true? is that what you're asking or do you mean something else?

the answer is c. 23/3
