Mega Movies hosted a film premiere on Friday night. They charged $8 for adults and $4 for children. One hundred seventy-three adults and children attended, and $1,276 was made in ticket sales. How many children and how many adults went to the film premiere?
Let a be the number of adults and c be the number of children
a + c = 173 => a =173 - c
8a + 4c = 1276
now substitute 173-c for a in the second equation and solve it.
