Question: The government donated tons of sand to four Cities. City A received 16 1/2 tons of sand, City B received 26 tons of sand, and City C received 24 1/2 tons of sand. The supplier lost the data for City D; however, they know the total for all four cities was 95 tons. How many tons of sand did City D receive?
Answer: Step-by-step reasoning process: The total tons of sand donated to City A and City C is 16 1 / 2 + 24 1 / 2 = 41. The total tons of sand donated to City A, City B, and City C is 41 + 26 = 67. Therefore, City D received 95 - 67 = 28 tons of sand.
So the answer is 28.

Question: It will take Richard and Sarah 3 years to save enough for a down payment on a house at their current rates. If the house's downpayment is $108000, calculate the amount each person saves per month if they share the monthly savings.
Answer: Step-by-step reasoning process: If they are to save every month for three years to reach the target amount, and each year has 12 months, they'll save for 12 * 3 = 36 months. If the house's downpayment is $108000, the total amount they both save per month is $108000 / 36 = $3000 every month. Since they share the monthly savings, each person will pay $3000 / 2 = = $1500.
So the answer is 1500.

Question: Joel is 5 years old and his dad is 32 years old. How old will Joel be when his dad is twice as old as him?
Answer: Step-by-step reasoning process: The difference in age between Joel and his dad is 32 - 5 = 27 years. When you double this gap in years, you have 27 x 2 = 54. When his dad is 54, Joel will be 54 / 2 = 27 years old.
So the answer is 27.
