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? Give the rationale and then the answer.
Let's think step by step. 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 is: 29.

Mr. Dore bought $140 worth of pants, a $43 shirt and a $15 tie. He pays with a $200 bill. How much will the saleswoman give him back? Give the rationale and then the answer.
Let's think step by step. The total expenses are $140 + $43 + $15 = $198. Mr. Dore paid $200, so the saleswoman must give him $200 - $198 = $2 back.. The answer is: 2.

Julia is performing in her high school musical this weekend and her family wants to come to the show. Tickets are $12 for adults and $10 for children. If her mom, dad, grandma, and three little sisters come to the show, how much will the total be for their tickets? Give the rationale and then the answer.
Let's think step by step. The cost will for 3 adults will be $12 / adult x 3 adults = $36. The cost for 3 children will be $10 / child x 3 children = $30. The total cost will be $36 + $30 = $66.. The answer is: 66.
