To determine what the ratio 10:18 represents, we first need to calculate the total number of each type of lunch option provided.
From the data given:
- Vegetarian Sandwich: 3
- Turkey Sandwich: 7
- Pepperoni Pizza: 8
- Cheese Pizza: 10
First, we can calculate the total number of sandwiches and pizzas.
Total Sandwiches: Vegetarian + Turkey = 3 + 7 = 10 sandwiches
Total Pizzas: Pepperoni + Cheese = 8 + 10 = 18 pizzas
Now we can analyze the ratio 10:18. This ratio represents:
Total Sandwiches : Total Pizzas = 10 : 18
Now, let's match this with the provided options:
- All Sandwiches : All Pizza - This is correct.
- All Pizza : All Sandwiches - This is not correct.
- All Lunches : Cheese Pizza - This doesn't match, since all lunches total to 38 (3 + 7 + 8 + 10) and it’s not a 10:18 ratio.
- Cheese Pizza : All Lunches - This doesn't match either.
Therefore, the correct answer is:
All Sandwiches : All Pizza
