Question

in a random sample of 250 frozen pepperoni pizzas of a particular brand, 7 do not have enough pepperoni slices. at this rate, how many of 12,000 frozen pepperoni pizzas of the same brand will not have enough pepperoni slices?

Explanation:

Step1: Set up proportion

Let \(x\) be the number of pizzas out of \(12000\) that do not have enough pepperoni. The proportion is \(\frac{7}{250}=\frac{x}{12000}\).

Step2: Cross - multiply

Cross - multiplying gives \(250x = 7\times12000\).

Step3: Solve for \(x\)

First, calculate \(7\times12000 = 84000\). Then \(x=\frac{84000}{250}\).
\(x = 336\).

Answer:

\(336\)
