polet [3.4K]

Answer:

The number of pizzas sold during A- lunch is 64

Step-by-step explanation:

Let us solve the question using the ratio method

∵ The ratio of pizza to nachos sold during A-lunch is 4 to 3

∵ There were 48 nachos sold

→ By using the ratio method

→ Pizza  :  Nachos

→  4        :   3

→  x        :  48

→ use the cross multiplication

∵ x × 3 = 4 × 48

∴ 3x = 192

→ Divide both sides by 3

∵ \frac{3x}{3} = \frac{192}{3}

∴ x = 64

∴ The number of pizzas sold during A- lunch is 64
