One weekend, there were 87 pizzas ordered for the sophomore dorm.
That weekend 18 customers ordered their pizza with just pepperoni,19 customers ordered their pizza with just sausage, 14 ordered theirs with just onions, 12 ordered theirs with pepperoni and sausage, 9 ordered theirs with sausage and onions, 6 ordered theirs with pepperoni and onions, and 2 ordered theirs with all three items. The remaining pizzas were cheese pizzas with no toppings. How many customers ordered at most two toppings on their pizza?
A)27
B)85
C)26
D)78
I answered A)27 at most two toppings.
Pepperoni and sausage 12 + sausage and onion 9 + Pepperoni and onions 6 = 27 ?
and 7 for remaining pizzas with no toppings.
i am a bit confused with the question and would appreciate any logic help.
