sweet [91]

Answer:

  • 207.5 adult
  • 52.5 children

Step-by-step explanation:

  a = 207.5 . . . . . . . . smoothies sold to adults

  260-a = 52.5 . . . . . smoothies sold to children

_____

For the given numbers, this is the way it works out. The "half" values suggest there is a typo somewhere, possibly in the curriculum material. Talk to your teacher about this one.
