Question

mancinis pizzeria sells four types of pizza crust. last week, the owner tracked the number sold of each type, and this is what she found.

type of crust	number sold
thick crust	238
stuffed crust	166
pan style	186

based on this information, of the next 4500 pizzas she sells, how many should she expect to be pan style? round your answer to the nearest whole number. do not round any intermediate calculations.
pizzas

Explanation:

Step1: Calculate total pizzas sold

First, we find the total number of pizzas sold last week by adding the number of each type: \( 328 + 238 + 166 + 186 \)
\( 328+238 = 566 \), \( 166 + 186 = 352 \), then \( 566+352 = 918 \)

Step2: Find the proportion of pan - style pizzas

The proportion of pan - style pizzas is \( \frac{186}{918} \)

Step3: Calculate expected pan - style pizzas

To find the expected number of pan - style pizzas in the next 4500 pizzas, we multiply the proportion by 4500: \( \frac{186}{918}\times4500 \)
First, simplify \( \frac{186}{918}=\frac{31}{153} \) (dividing numerator and denominator by 6)
Then \( \frac{31}{153}\times4500=\frac{31\times4500}{153}=\frac{139500}{153}\approx911.76 \), rounding to the nearest whole number gives 912.

Answer:

912
