Answer:

  • 72

Step-by-step explanation:

Cost of each item:

  • Pizza = $1.50, Hotdogs = $1.25

Number of each item:

  • Pizza = x, Hotdogs = x + 20

Total cost:

  • 1.25x + 1.5(x + 20) = 173
  • 1.25x + 1.5x + 30 = 173
  • 2.75x = 143
  • x = 143/2.75
  • x = 52

Number of slices of pizza:

  • 52 + 20 = 72
