Answer:  (b)  19 pizzass had only a mushroom topping.

The student needs to recognize number sense and know how to add, subtract, multiply and divide mathematical expressions.

In order to solve this problem, it is important to realize that the total number of pizza’s were 35 and since 16 had only pepperoni that means that the student must subtract 16 from the total of 35 to obtain the number of pizza’s with the mushroom topping.

35 – 16 = 19 pizzas with a mushroom topping.
