Answer:

Step-by-step explanation:

Given:

Ratio of time for which Pepperoni pizza and cheese pizza should be baked is given as:

P = 3C - 2

Where P is the time for which pepperoni pizza should be baked and

C is the time for which Cheese pizza should be baked.

In other words, we are given that: C=12\ min

To find:

For how long small pepperoni pizza should be baked ?

P=?

Solution:

Let us put the value of C in the equation of the model.

P = 3C - 2

\Rightarrow P = 3\times 12 - 2\\\Rightarrow P = 36 - 2\\\Rightarrow P = \bold{34\ min}

Therefore, a small pepperoni pizza should be baked for <em>34 minutes</em>.
