We have a question: A building has 20 floors. Each floor is 3 meters high, except for the last two floors. The last two floors are each 0.5 meters higher. How tall is the building?
And an answer: 61
So how you got the answer?
There are 20 - 2 = 18 floors that are each 3 meters high. So the first 18 floors is 18 x 3 = 54 meters high. The last two floors are each 3 + 0.5 = 3.5 meters high. So the total height of the last two floors is 3.5 x 2 = 7 meters. Therefore, the building is 54 + 7 = 61 meters high.

We have a question: Maddy was given 40 chocolate eggs for Easter. She likes to eat two each day after school. If Maddy has two chocolate eggs after school each day, how many weeks will they last?
And an answer: 4
So how you got the answer?
Maddy is eating 2 eggs each day after school and there are 5 school days in a week, so she eats 2 x 5 = 10 eggs each week. Since Maddy has 40 eggs / 10 eggs each week, they will last 4 weeks.

We have a question: Ravi has some coins. He has 2 more quarters than nickels and 4 more dimes than quarters. If he has 6 nickels, how much money does he have?
And an answer: 350
So how you got the answer?
Ravi has 6 + 2 = 8 quarters. He has also 8 + 4 = 12 dimes. A nickel is worth 5 cents so Ravi's nickels amount to 6 x 5 = 30 cents. A quarter is worth 25 cents so his quarters amount to 8 x 25 = 200 cents. A dime is worth 10 cents so his dimes amount to 12 x 10 = 120 cents. therefore, Ravi has 30 + 200 + 120 = 350 cents.
