She counts 45 fish on day 2 because 3 x 15 = 45. She counts 60 fish in total because 15 + 45 = 60. She counts 15 sharks because 60 x .25 = 15.
The answer: 15
Reverse engineering the question: Mabel is counting sharks in the ocean. She knows that of the fish that she sees, 25% will be sharks and 75% will be another type of fish. On day one she counts 15 fish. On day 2 she counts three times as many. How many sharks did she count over those two days?

The 12 cans of Spam costs $3 x 12 = $36. The total amount of 3 jars of peanut butter is $5 x 3 = $15. And the total amount of the 4 loaves of bread is $2 x 4 = $8. Therefore the total amount he will have to pay is $36 + $15 + $8 = $59.
The answer: 59
Reverse engineering the question: Granger went to the grocery store. He saw that the Spam is $3 per can, the peanut butter is $5 per jar, and the bread is $2 per loaf. If he bought 12 cans of spam, 3 jars of peanut butter, and 4 loaves of bread, how much is the total amount he paid?

Jen scored 20 + 10 = 30 on the exam. Sammy scored two less, so his score was30 - 2 = 28. Thus, Sammy made 35 - 28 = 7 mistakes.
The answer: 7
Reverse engineering the question: Bryan's score on a math exam is 20. Jen scored 10 more than Bryan while Sammy scored 2 fewer than Jen. If the math exam has 35 points in all, how many mistakes did Sammy make?


If Anthony has 12 pets, the number of cats is 2 / 3 * 12 pets = 8 cats. The number of dogs that Anthony have is 12 pets - 8 cats = 4 dogs. Leonel has 1 / 2 * 8 cats = 4 cats. If Leonel has seven more dogs than Anthony, then he has 4 dogs + 7 dogs = 11 dogs. The total number of pets the two have is 11 dogs for Leonel + 4 cats for Leonel + 4 dogs for Anthony + 8 cats for Anthony = 27.
The answer: 27
Reverse engineering the question:
