a group of adults plus one child attend a movie and Cineplex 15. tickets cost $19 for adults and $6 for children the total cost for the movie is $78 write an equation to find the number of adults in the group
We're told that one child attended, meaning we can subtract $6 from the total of $78. Then we just need to divide $72 by 19. These numbers leave you with an incomplete adult but it is the correct equation.
