81 cups of tomato
To find the number of cups of tomato needed, we first calculate the total number of parts in the extended ratio by adding the parts for green pepper, onion, and tomato: 1 + 3 + 9 = 13 parts.
Next, we find the number of cups of tomato needed by dividing the total number of parts into the total amount of salsa: 117 cups / 13 parts = 9 cups per part.
Finally, we multiply the number of cups of tomato per part by the number of parts for tomato: 9 cups/part * 9 parts = 81 cups of tomato needed.
