Expii is having a pizza party and we need help figuring out how many pizzas to get. Each pizza has eight slices.

  • Alex wants a whole pizza.
  • Allison wants double the slices that Michelle wants.
  • Andrea doesn't want any pizza because it's from Pittsburgh.
  • Arnold wants half of what Alex wants.
  • Elise wants triple the number of slices that Zach wants.
  • Grace wants the square of the number of slices Arnold wants, minus the number of slices Allison wants.
  • Mark wants three more than double the number of slices Andrea wants.
  • Michelle wants two thirds the number of slices Elise wants.
  • Po wants the fourth prime number above the number of slices that Tori wants.
  • Tori wants double the number of slices that Mark wants minus the number of slices that Michelle wants.
  • Zach wants the square root of the difference of slices between Grace and Arnold.
