Question: It takes 320 rose petals to make an ounce of perfume. If each rose produces 8 petals, and there are 12 roses per bush, how many bushes will Fern have to harvest to make 20 12-ounce bottles of perfume?
Answer with step-by-step thinking: First find the number of roses needed for one ounce of perfume: 320 petals / 8 petals / rose = 40 roses. Then multiply the number of roses needed for one ounce by the number of ounces per bottle to find the number of roses per bottle: 40 roses / ounce * 12 ounces / bottle = 480 roses / bottle. Then multiply that number by the number of bottles to find the total number of roses needed: 480 roses / bottle * 20 bottles = 9600 roses. Then divide that number by the number of roses per bush to find the number of bushes Fern needs to harvest: 9600 roses / 12 roses / bush = 800 bushes.
So the answer is 800.


Question: Loraine makes wax sculptures of animals. Large animals take four sticks of wax and small animals take two sticks. She made three times as many small animals as large animals, and she used 12 sticks of wax for small animals. How many sticks of wax did Loraine use to make all the animals?
Answer with step-by-step thinking:
Loraine made 12 / 2 = 6 small animals. She made 6 / 3 = 2 large animals. She used 2 * 4 = 8 sticks of wax on large animals. Therefore, Loraine used 12 + 8 = 20 sticks of wax for all the animals.
So the answer is 20.
