Question

PLEASE HELP ME



Mega Movies hosted a film premiere on Friday night. They charged $8 for adults and $5 for children. One hundred thirty adults and children attended, and $986 was made in ticket sales. How many children and how many adults went to the film premiere?

15 children; 115 adults
18 children; 112 adults
12 children; 118 adults
22 children; 108 adults

Answer 1

a - adults
c - children

we have:

8*a + 5*c = 986
a+c=130

so we can solve for c:
a= 130-c

8*(130-c) + 5*c = 986
1040-8c+5c=986
1040-3c=986
c=18

so b.
