Using proportions, it is found that out of the next 1500 pizzas, she should expect 420 pan style pizzas.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The proportion of pan style pizzas is given as follows:
294/(284 + 313 + 159 + 294) = 0.28.
Hence, out of 1500 pizzas, this amount is equivalent to:
0.28 x 1500 = 420
