[Question]Sol sells candy bars to raise money for her softball team. On the first day, she sells ten candy bars and sells four more candy bars than she sold the previous day each day afterward. If she sells six days a week and each candy bar costs 10 cents, how much will she earn in a week in dollars?
[Answer]Sol will sell 10 + 4 = 14 candies on the second day. She will sell 14 + 4 = 18 candies on the third day. She will sell 18 + 4 = 22 candies on the fourth day. She will sell 22 + 4 = 26 candies on the fifth day. She will sell 26 + 4 = 30 candies on the sixth day. She will sell a total of 10 + 14 + 18 + 22 + 26 + 30 = 120 candies in a week. Hence, she will earn 120 x 10 = 1200 cents. Since 1 dollar is equal to 100 cents, then Sol will earn 1200 / 100 = $12. The answer is 12.
Q: Ali, Nada, and John have a total of $67 in their wallets. Ali has $5 less than Nada and John has 4 times more than Nada. How much money does John have?
A: Let's say that N is what Nada has, J is what John has, and A is what Ali has. We know that A = N - 5 and J = 4N. We also know that: N + A + J = $67. We can substitute the equations from step 1 into the equations from step 2 to get: N + 4N + (N - 5) = $67. Combining like terms gets us 6N - 5 = $67. So, N = ($67 + 5) / 6 = $12. Substituting $12 back into the equation J = 4 N, we find John has 4 x 12 = $48. The answer is 48.
Question: 5 squirrels collected 575 acorns. If each squirrel needs 130 acorns to get through the winter, how many more acorns does each squirrel need to collect?
Answer: Each squirrel now has 575 / 5 = 115 acorns. Each squirrel still needs to collect another 130 - 115 = 15 acorns. The answer is 15.
[Question]A pet store has six dogs for sale. They have half as many cats, twice as many birds, and thrice as many fish for sale. How many animals are for sale in the pet store?
[Answer]The pet store has 6 / 2 = 3 cats for sale. They have 6 x 2 = 12 birds for sale. They have 6 x 3 = 18 birds for sale. Therefore, there are a total of 6 + 3 + 12 + 18 = 39 pets for sale. The answer is 39.
Q: Lavinia’s daughter is 10 years younger than Katie’s daughter. Lavinia’s son is 2 times the age of Katie’s daughter. If Katie’s daughter is 12 years old, how many years older is Lavinia’s son than Lavinia’s daughter?
A: Lavinia’s daughter is 12 - 10 = 2 years old. Lavinia’s son is 12 * 2 = 24 years old. Lavinia’s son is 24 - 2 = 22 years older than Lavinia’s daughter. The answer is 22.
Question: Lucille is painting her room. Two of her walls are 3 meters wide and 2 meters tall. The third wall is 5 meters wide and 2 meters tall. The final wall is 4 meters wide and 2 meters tall. If each can of paint covers 2 square meters, how many cans of paint does Lucille need?
Answer:
For the first set of walls, each wall covers 3 meters wide * 2 meters tall = 6 square meters. There are two of these walls, so this becomes a total of 6 meters * 2 walls = 12 square meters. The third wall covers 5 meters wide * 2 meters tall = 10 square meters. The final wall covers 4 meters wide * 2 meters tall = 8 square meters. So in total, the paint needs to cover 12 + 10 + 8 = 30 metres. Since each can covers 2 meters, Lucille needs 30 meters / 2 = 15 cans of paint. The answer is 15.
