The total monthly bill for 30 Mbps is $20 x 2 = $40. She will have to pay $40 x 12 = $480 every year for 30mbps. The total monthly bill for 20 Mbps is $20 + $10 = $30. So, she will have to pay $30 x 12 = $360 for 20 Mbps per year. Therefore the amount she will save per year if she chooses the 20mbps is $480 - $360 = $120.
The answer: 120
Reverse engineering the question: Marites internet speed is 10 megabits per second and her monthly internet bill is $20. Marites is planning to upgrade her service and choosing between 20 Mbps and 30 Mbps. If the price of the 30 Mbps is twice the amount of her current monthly bill and the price of the 20 Mbps is $10 more than her current monthly bill, how much will she save per year if she chooses the 20 Mbps than 30 Mbps?


Reasoning and answer: First find how much barbecue sauce Jack makes by adding the volume of each ingredient: 3 cups + 1 cup + 1 cup = 5 cups. Then multiply the number of pulled pork sandwiches by the amount of sauce per sandwich to find the total amount used: 1 / 6 cup / sandwich * 18 sandwiches = 3 cups. Then subtract this amount from the total amount of sauce Jack has to find how much he uses on the burgers: 5 cups - 3 cups = 2 cups. Then divide this amount by the amount of sauce used per burger to find the number of burgers he can make: 2 cups / 1 / 4 cup / burger = 8 burgers.
The answer: 8

Question: Jack is making barbecue sauce. He uses 3 cups of ketchup, 1 cup of vinegar and 1 cup of honey. If each burger takes 1/4 cup of sauce and each pulled pork sandwich takes 1/6 cup, how many burgers can Jack make if he makes 18 pulled pork sandwiches?


First find how much faster the dog is than the sheep: 20 feet / second - 12 feet / second = 8 feet / second. Then divide the distance the dog needs to run by the speed difference: 160 feet / 8 feet / second = 20 seconds.
The answer: 20
Reverse engineering the question: Mary's sheep can run 12 feet per second, and her sheepdog can run 20 feet per second. A sheep standing 160 feet away from the sheep dog bolts, and the dog runs after it. How many seconds does it take the dog to catch the sheep?


Reasoning and answer: In her hamper, Brie has 12 x 75% = 9 blouses. In her hamper, she has 6 x 50% = 3 skirts. In the hamper, she has 8 x 25% = 2 slacks. She will need to wash 9 + 3 + 2 = 14 pieces of clothes.
The answer: 14
What was the question?
Question: When all her clothes are washed and in her closet, Brie has 12 blouses, 6 skirts, and 8 slacks. Today in her hamper, she has 75% of her blouses, 50% of her skirts, and 25% of her slacks. How many pieces of clothing will she need to put in the washer?


With 4 apples, Steven will collect 4 apples * 6 seeds / apple = 24 seeds. With 3 pears, Steven will collect 3 pears * 2 seeds / pear = 6 seeds. With 9 grapes, Steven will collect 9 grapes * 3 seeds / grape = 27 seeds. In total, Steven will collect 24 seeds + 6 seeds + 27 seeds = 57 seeds. To collect 60 seeds he needs 60 seeds - 57 seeds = 3 more seeds.
The answer: 3
Reverse engineering the question: Steven's teacher sends the class an assignment to collect 60 different fruit seeds. Apples average 6 seeds, pears average 2 seeds, and grapes average 3 seeds. Steven has set aside 4 apples, 3 pears, and 9 grapes to extract their seeds. How many more seeds does he need to fulfill his assignment?


Olivia made $9 * 4 hours = $36 on Monday. Olivia made $9 * 3 = $27 on Wednesday. Olivia made $9 * 6 hours = $54 on Friday. For the week Olivia made $36 + $27 + $54 = $117.
The answer: 117
Reverse engineering the question:
Olivia earns $9 per hour. She worked 4 hours on Monday, 3 hours on Wednesday and 6 hours on Friday. How much money did Olivia make this week?
