Another interesting DS question. OA after a few reply.
Beth’s pizzeria offers x different toppings. What is the value of x?
(1) There are an equal number of different pizzas that can be made with (x − 2) toppings as there are different pizzas with just 2 toppings.
(2) If the pizzeria were to add one additional topping, the number of different pizzas that could be made with 4 toppings would double.
