A culinary club earns $1116 from a dinner service. They sold 32 adult meals and 60 student meals. An adult meal costs twice as much as a student meal. What is the cost of an adult meal? Please explain and show all steps! The answer is 18, but I don't get how.

  $18

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.

Additional comment

You can instead use a variable for the cost of a student meal, or you can use variables for both:

  a = 2s

  32a +60s = 1116

It makes sense here to solve this by eliminating the s variable in any of several ways, since you ultimately want to know the value of 'a'.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
