The list below shows the different pizzas sold by noon at a local pizza shop.

Pepperoni: 11
Supreme: 7
Cheese: 6
Hawaiian: 3
Based on these results, if 189 pizzas were sold by the end of the day, how many pizzas could be expected to be cheese?

1 answer

To find out the expected number of cheese pizzas sold, we need to first calculate the total number of pizzas sold for all types.

Total pizzas sold = 11 (Pepperoni) + 7 (Supreme) + 6 (Cheese) + 3 (Hawaiian) = 27

Next, we can find the proportion of pizzas sold that were cheese:

Cheese pizzas sold / Total pizzas sold = 6 / 27

To find out how many cheese pizzas would be expected if 189 pizzas were sold, we can set up a proportion:

Cheese pizzas expected / 189 = 6/27

Solving for Cheese pizzas expected:

Cheese pizzas expected = (189 * 6) / 27 = 42

Therefore, we can expect approximately 42 cheese pizzas to be sold by the end of the day if 189 pizzas were sold in total.
