First we calculate the number of flowers: 250 + 375 + 320 = 945. Then the expense: 945 X 2 = 1890. So, the total expenditure is 1890.
The answer: 1890
Reverse engineering the question: It's spring! The gardener at Parc Municipal orders flowers. He takes 250 tulips, 375 carnations and 320 roses. Each flower is sold for 2. Calculate the total expenses.
Reasoning and answer: First find Karen's net speed by subtracting the speed of the current: 10 mph - 4 mph = 6 mph. Then divide the length of the river by Karen's speed to find how long it takes her to paddle up it: 12 miles / 6 mph = 2 hours.
The answer: 2
What was the question?
Question: Karen is paddling her canoe up a river against the current. On a still pond, Karen can paddle 10 miles per hour. The river flows in the opposite direction at 4 miles per hour. If the river is 12 miles long, how many hours will it take Karen to paddle up it?
Seafoam Valley has 2 / 3 as many skirts as Azure Valley, or (2 * 60) / 3 = 120 / 3 = 40 skirts. Purple Valley has 1 / 4 as many skirts as Seafoam Valley, or 40 / 4 = 10 skirts.
The answer: 10
Reverse engineering the question: Purple Valley has one-quarter as many skirts as Seafoam Valley, and Seafoam Valley has two-thirds as many skirts as Azure Valley. If Azure Valley has 60 skirts, how many skirts does Purple Valley have?
Reasoning and answer: Before the typhoon, their farm had a total of 50 trees + 30 trees = 80 trees. If there was 1 more than Mahogany than Narra tree that fell, then this means there were 2 Narra trees and 2 + 1 = 3 Mahogany trees that fell during the typhoon. So, Bea's mom planted 2 trees x 2 = 4 Narra trees. She also planted 3 trees x 3 = 9 Mahogany trees. So, her mom planted 4 trees + 9 trees = 13 more trees. After the typhoon, they only had 80 trees - 5 trees = 75 trees left. Therefore, there are 75 trees + 13 trees = 88 trees now.
The answer: 88
What was the question?
Question: Bea's mom planted 50 Mahogany and 30 Narra trees on their farm. Due to a typhoon, a total of 5 trees fell. One more Mahogany tree fell than the number of Narra trees that fell. A month after the typhoon, Bea's mom planted twice as much as the number of the Narra and thrice the number of Mahogany trees that fell. How many trees are now on the farm?
Rhonda caught half as many necklaces as did Boudreaux, or 12 / 2 = 6 necklaces. Three times as many necklaces as Rhonda caught is 6 * 3 = 18 necklaces. Thus, Latch caught four less than three times as many necklaces as did Rhonda, for a total of 18 - 4 = 14 necklaces.
The answer: 14
Reverse engineering the question: During the Mardi Gras parade, Latch caught four less than three times as many necklaces as did Rhonda. If Rhonda caught half as many necklaces as did Boudreaux, and Boudreaux caught twelve necklaces, how many necklaces did Latch catch?
Darla:6 books. Katie:6 / 2 = 3 books. Gary: 5(6 + 3) = 45 books. 6 + 3 + 45 = 54 books.
The answer: 54
Reverse engineering the question:
Darla has 6 books in her locker. Katie has half as many books as Darla, and Gary has 5 times the number of books that Darla and Katie have combined. How many books do the three have total?
