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?
What is the solution?
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
