Question

a salsa recipe uses green pepper, onion, and tomato in the extended ratio 3 : 5 : 7. How many cups of tomatos are needed to make 105 cups of salsa

Answer 1

Let's take cups of green pepper, onion and salsa to be 3x, 5x and 7x.

In this case, 3x + 5x + 7x = 105

15x = 105

therefore x = 105/15 = 7

cups of tomatoes = 7x = 7 multiplied by 7 = 49
