Answer:

  • x +y = 14
  • 8x +3y =72

Step-by-step explanation:

The variables are defined, so we only need to express the given relations. The total of the two quantities is 14.

  x + y = 14

The sum of costs is $72. Totts are $8 each, so x of them will cost 8x. Elentines are $3 each, so y of them will cost 3y.

  8x +3y = 72
