Answer this question:John's piggy bank contains quarters, dimes, and nickels. He has three more dimes than quarters and 6 fewer nickels than quarters. If he has 63 coins, how many quarters does John have?
Let x represent the number of quarters John has. Nickels: x - 6. Dimes: x + 3. Total:x + x - 6 + x + 3 = 63. 3x - 3 = 63. 3x = 66. x = 22 quarters.
The answer is 22.

Answer this question:Mrs. Fredrickson has 80 chickens where 1/4 are roosters and the rest are hens. Only three-fourths of those hens lay eggs. How many chickens does Mr. Fredrickson have that do not lay eggs?
Mrs. Fredrickson has 80 x 1 / 4 = 20 roosters. So he has 80 - 20 = 60 hens. Only 60 x 3 / 4 = 45 of the hens lay eggs. Thus, 60 - 45 = 15 hens do not lay eggs. Therefore, Mr. Fredrickson has a total of 15 hens + 20 roosters = 35 chickens that do not lay eggs.
The answer is 35.

Answer this question:Ishmael was monitoring whales out at sea for conservation purposes. Each time he takes a trip to sea, he sees a different group of whales. On his first trip, he counts 28 male whales and twice as many female whales. On his second trip, he sees 8 baby whales, each travelling with their parents. On his third trip, he counts half as many male whales as the first trip and the same number of female whales as on the first trip. In total, how many whales were out at sea during Ishmael’s monitoring?
On the first trip, Ishmael sees 28 male whales * 2 = 56 female whales. So in total, he sees 28 male whales + 56 female whales = 84 whales on the first trip. On the second trip, each baby whale travels with its parents which means it travels in a group of 1 baby whale + 2 parents = 3 whales / baby whale. This means there are 8 baby whales * 3 whales / baby whale = 24 whales on the second trip. On the third trip, there are half as many male whales as there were on the first trip, so there must be 28 male whales / 2 = 14 male whales. Adding this to the female whales means he saws 14 males whales + 56 female whales = 70 whales on the third trip. In total, Ishmael saw 84 + 24 + 70 = 178 whales across the three trips.
The answer is 178.

Answer this question:Eliana walked 200 steps for her morning exercise, did some press-ups, then added some 300 more steps to her count for the first day. The next day, she walked twice the number of steps she walked on the first day. And on the third day, Eliana walked an additional 100 steps. What's the total number of steps Eliana walked during these three days?

On the first day, she walks 200 + 300 = 500 steps. The next day she walks twice the steps, which is 2 * 500 = 1000. The total number of steps after the two days are 1000 + 500 = 1500. On the third day, she walks an additional 100 steps, bringing the three - day total to 1500 + 100 = 1600 steps.
The answer is 1600.
