Answer:
63
Explanation:
You are using the ratio 2:7, cheese pizzas to pepperoni pizzas. You must multiply the ratio by the same numbers, or the ratio will become unproportional. The question states that 35 more pepperoni pizzas were sold than cheese. If we multiply the ratio by 7, we would have 14:49. The range in that is 35, so that means that 35 more pepperoni pizzas were sold. Because you are trying to find how many total pizzas were sold, you need to add 14 and 49 together to get a grand total of 63.
