Question

izzos pizza sells four types of pizza crust. last week, the owner tracked the number sold of each type, and this is what she found. based on this information, of the next 1500 pizzas she sells, how many should she expect to be stuffed crust? round your answer to the nearest whole number. do not round any intermediate calculations.

Explanation:

Step1: Calculate total number of pizzas sold last week

To find the total number of pizzas sold, we sum up the number of each type of crust sold. So we add \(493 + 222 + 172 + 188\).
\(493+222 = 715\), \(715 + 172=887\), \(887+188 = 1075\). So the total number of pizzas sold last week is \(1075\).

Step2: Find the proportion of stuffed crust pizzas

The number of stuffed crust pizzas sold is \(172\), and the total number of pizzas sold is \(1075\). So the proportion of stuffed crust pizzas is \(\frac{172}{1075}\).

Step3: Calculate the expected number of stuffed crust pizzas in 1500 sales

We multiply the proportion of stuffed crust pizzas by the number of pizzas to be sold (1500). So we calculate \(1500\times\frac{172}{1075}\).
First, \(1500\times172 = 258000\), then divide by \(1075\): \(\frac{258000}{1075}\approx239.999\approx240\) (rounded to the nearest whole number).

Answer:

240
