Allie, Rob, and Allyn each bought a bowl of grapes. Allie's bowl contained two more grapes than Rob's bowl. Allyn's bowl contained four more grapes than Allie's bowl. If Rob's bowl contained 25 grapes, what is the total combined number of grapes in all three bowls?
Let's think: If Allie's bowl contained two more grapes than Rob's bowl, there were 25 + 2 = 27 grapes in Allie's bowl. If Allyn's bowl contained four more grapes than Allie's bowl, there were 27 + 4 = 31 grapes in Allyn's bowl. The total combined number of grapes in all three bowls is 25 + 27 + 31 = 83 grapes.. The answer is: 83.

In a math contest, Riley and Ofelia are on one team. The team's final score is obtained by adding the scores of the students of the same team. Out of the 35 questions, Riley got 3 mistakes while Ofelia got 5 more than half the score of Riley. How many incorrect answers did their team get?
Let's think: Riley's score is 35 - 3 = 32. Half of Riley's score is 32 / 2 = 16. So Ofelia's score is 16 + 5 = 21. Hence, Ofelia got 35 - 21 = 14 incorrect answers. Therefore, their team got 3 + 14 = 17 incorrect answers.. The answer is: 17.

Wendi lives on a plot of land that is 200 feet by 900 feet of grassland. She raises rabbits on her property by allowing the rabbits to graze on the grass that grows on her land. If one rabbit can eat enough grass to clear ten square yards of lawn area per day, and Wendi owns 100 rabbits, how many days would it take for Wendi's rabbits to clear all the grass off of her grassland property?
Let's think: One square yard is the same as 3 feet by 3 feet, or 3 * 3 = 9 square feet. Ten square yards is 9 * 10 = 90 square feet. Therefore, 100 rabbits can clear 100 * 90 = 9,000 square feet of grassland per day. A 200 ft by 900 ft area is 200 * 900 = 180,000 square feet. Thus, 180,000 sq ft can be cleared by 100 rabbits in 180,000 / 9000 = 20 days.. The answer is: 20.

It takes Jason 30 minutes to cut 1 lawn in his neighborhood. If he cuts 8 yards on both Saturday and Sunday, how many hours does he spend cutting grass?
Let's think:
He cuts 8 yards on both Saturday and Sunday so that's 2 * 8 = 16 yards. It takes him 30 minutes to cut 1 yard so it takes him 30 * 16 = 480 minutes. There are 60 minutes in 1 hour and it takes him 480 minutes so that's a total of 480 / 60 = 8 hours.. The answer is: 8.
