Answer this question:Bob has planted corn in his garden, and it has just started to sprout. A week after planting it, it had grown 2 inches. The next week, its height increased by twice as much as it had the first week. In the third week, it grew 4 times as much as it did the week before. How tall are the corn plants now?
The second week it grew twice as much as the first week, so 2 * 2 inches = 4 inches. The third week it grew 4 times as much as in the second week, so 4 * 4 inches = 16 inches. In total, it grew 2 inches + 4 inches + 16 inches = 22 inches.
The answer is 22.

Answer this question:James decides to make a bathtub full of jello. For every pound of water, you need 1.5 tablespoons of jello mix. The bathtub can hold 6 cubic feet of water. Each cubic foot of water is 7.5 gallons. A gallon of water weighs 8 pounds. A tablespoon of jello mix costs $0.50. How much did he spend to fill his tub?
The tub has 6 * 7.5 = 45 gallons. That would weigh 45 * 8 = 360 pounds. So he needs 360 * 1.5 = 540 tablespoons of jello mix. So he spent 540 * .5 = $270.
The answer is 270.

Answer this question:Chris wants to hold his breath underwater for 90 straight seconds so he starts training each day. On the first day, he holds it for 10 seconds. On the second day, he holds it for 20 seconds. On the third day, he holds it for 30 seconds. After realizing that he can hold it for ten extra seconds each day, he realizes he can calculate how many days it is until he reaches 90 if he keeps up the same pace. So how many days until he can hold his breath for 90 seconds?
He still has to improve by 60 more seconds because 90 - 30 = 60. This will take 6 days because 60 / 10 = 6.
The answer is 6.

Answer this question:Madeline has 10 flowers. If 4 flowers are red, 2 flowers are white, and the rest are blue, what percentage of flowers are blue?
There are 4 + 2 = 6 flowers that are not blue. Thus, there are 10 - 6 = 4 blue flowers. Thus, blue flowers make up (4 / 10) * 100 = 40%.
The answer is 40.
