Answer 1

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
