Q: Zilla spent 7% of her monthly earnings on rent, half of it on her other monthly expenses, and put the rest in her savings. If she spent $133 on her rent, how much does she deposit into her savings account in a month?
A: Since $133 is equal to 7% of her earnings, then 1% is equal to $133 / 7 = $19. The total monthly earning of Zilla is represented by 100%, so $19 x 100 = $1900 is her monthly earnings. So, $1900 / 2 = $950 is spent on her other monthly expenses. The total amount spent on the rent and other monthly expenses is $133 + $950 = $1083. Hence, she saves $1900 - $1083 = $817 per month. The answer is 817.
Question: Chantal knits sweaters to sell. Each sweater takes 4 balls of yarn. Each ball of yarn costs $6. How much money will Chantal gain in all 28 sweaters if she sells each sweater for $35?
Answer: The 28 sweaters need 28 x 4 = 112 balls of yarn. So, Chantal will spend 112 x $6 = $672 in all for the balls of yarn. Her total earnings for selling 28 sweaters is $35 x 28 = $980. Therefore, Chantal will gain $980 - $672 = $308. The answer is 308.
[Question]A volcano erupts and spews ash into the sky. The ash cloud spreads out in a diameter eighteen times as far as the distance it shot up into the sky. If the ashes erupted three hundred feet into the sky, what was the radius of the ash cloud in feet?
[Answer]The ash cloud spread out 300 * 18 = 5400 feet in diameter. The radius is half the diameter, so the ash cloud had a radius of 5400 / 2 = 2700 feet. The answer is 2700.
Q: One kilogram of tomatoes is 20% cheaper than one kilogram of cucumbers. One kilogram of cucumbers costs $5. What is the price of two kilograms of tomatoes and three kilograms of cucumbers?
A: One kilogram of tomatoes is 20 / 100 * 5 = $1 cheaper than one kilogram of cucumbers. This means that one kilogram of tomatoes costs 5 - 1 = $4. So two kilograms of tomatoes is a cost of 2 * 4 = $8. And three kilograms of cucumbers is a cost of 3 * 5 = $15. So the price for both products would be 8 + 15 = $23. The answer is 23.

Q: A pencil costs $0.5 each and a folder costs $0.9 each. An office needs two dozen pencils and 20 pieces of folders. How much does it cost to buy the office supplies?
A:
