Question: Rubble has $15 in his pocket and he needs to buy 2 notebooks and 2 pens. Each notebook cost $4.00 meanwhile each pen cost $1.50. How much money will be left from Rubble after the purchase?
Answer: The total cost of two notebooks is $4.00 x 2 = $8.00. The total cost of two pen $1.50 x 2 = $3.00. So, the total amount Rubble spent for all the stuff was $8.00 + $3.00 = $11.00. Therefore, Rubble was left off with $15.00 - $11.00 = $4.00. The answer is 4.

Question: It takes 15 minutes for Dante to go to Hidden Lake. From Hidden Lake, he has to walk back to the Park Office and it takes him 7 minutes. When he arrives there, he will have been gone from the Park Office 32 minutes altogether. If he had walked to the Lake Park restaurant from the Park office before taking the 15 minute walk to Hidden Lake, how long is the walk from Park Office to the Lake Park restaurant?
Answer: If it takes 15 minutes for Dante to go to Hidden Lake and 7 minutes to walk back to the Park Office, he spends a total of 15 + 7 = 22 minutes on the trip. When Dante arrives at the Park Office, he will have been gone from the Park Office 32 minutes altogether, and since he passed by the Lake Park restaurant from The Park Office, his walk from Park Office to the Lake Park restaurant took 32 - 22 = 10 minutes. The answer is 10.

Question: Denny is planning to build a modular home. A 400 square foot Kitchen module costs $20000 and a 150 square foot bathroom module costs $12,000. All other modules cost $100 per square foot. If Denny plans to build a 2,000 square foot modular home containing one kitchen and two bathrooms, how much will it cost, in dollars?
Answer: The kitchen and two bathroom modules will take up 400 + 150 + 150 = 700 sq. ft. of the 2000 sq. ft. of space. Thus, the remaining modular space is 2000 - 700 = 1300 sq. ft. Cost of the kitchens and bathrooms is $20,000 + $12,000 + $12,000 = $44,000. The cost of the other 1300 sq. ft. of space is 1300 * $100 = $130,000. In total, the cost of the complete 2000 sq.ft. modular home with one kitchen and two bathrooms is $44,000 + $130,000 = $174,000. The answer is 174000.

Larry's shoulder height is 20% less than 5 feet, or 0.2 * 5 = 1 foot less than 5 feet. One foot less than 5 feet is 5 - 1 = 4 feet. If Barry stands on Larry's shoulders, they can reach 4 + 5 = 9 feet. The answer is 9.
