Sabrina is collecting herbs to make a poultice for her grandmother. She needs twice as many basil leaves as sage leaves and 5 fewer sage leaves than verbena leaves. If she needs 12 basil leaves, how many leaves total does she need? Let's be accurate as possible.
First find the number of sage leaves Sabrina needs: 12 basil / 2 basil / sage = 6 sage. Then add 5 to find the total number of verbena leaves she needs: 6 sage + 5 = 11 verbena. Finally, add up all the different leaves to find the total number: 6 sage + 11 verbena + 12 basil = 29 leaves.
The answer: 29.
