Answer:
24 slices of pizza were available to be eaten
Step-by-step explanation:
Here, we want to get the number of slices of pizza available to be eaten

In each of the pizzas, there were 6 slices;
So the number of slices in 4 pizzas would be 6 * 4 = 24 slices
So, 24 slices of pizza were available to be eaten by the girls
