Step-by-step explanation:
Let x represent the cost of an adult meal (the value we want to know). The cost of a student meal is half that, or x/2. The total cost of all the meals is …
60(x/2) +32x = 1116
62x = 1116 . . . . . collect terms
x = 1116/62 = 18 . . . . divide by 62
The cost of an adult meal is \$18.
