Question

Mega Movies hosted a film premiere on Friday night. They charged $9 for adults and $6 for children. One hundred twenty-seven adults and children attended, and $1,053 was made in ticket sales. How many children and how many adults went to the film premiere?

Answer 1

X=adults and c=children
x+c=127
9x+6c=1,053
Multiply the first equation by negative 6.
-6x+(-6)c= -762
Add the equations together.
3x=291
x=97
97+c=127
c=30
There were 30 children and 97 adults.
