[Question]Darwin has 600$. He spent 1/3 of it on gas for his car, and 1/4 of what was left on food. How much money did he have left?
[Answer]600 / 3 = 200$ for gas. After buying gas, Darwin has 600 - 200 = 400$ left. 400 / 4 = 100$ on food. Darwin has 400 - 100 = 300$ left. The answer is 300.
Q: The moon has a surface area that is 1/5 that of Earth. The surface area of the Earth is 200 square acres. The land on the moon is worth 6 times that of the land on the Earth. If the total value of all the land on the earth is 80 billion dollars, what is the total value in billions of all the land on the moon?
A: If the moon land had the same value as earth land it would be worth 16 billion because 80 / 5 = 16. The moon's total land value is 96 billion because 16 x 6 = 96. The answer is 96.
Question: Sophie does 4 loads of laundry a week and uses 1 dryer sheet per load. A box of dryer sheets costs $5.50 and has 104 dryer sheets in a box. On her birthday, she was given wool dryer balls to use instead of dryer sheets. How much money does she save in a year not buying dryer sheets?
Answer: She does 4 loads of laundry a week and used 1 dryer sheet per load for a total of 4 * 1 = 4 dryer sheets in a week. She used 4 dryer sheets per week for 52 weeks for a total of 4 * 52 = 208 dryer sheets. Her box of dryer sheets has 104 sheets so she needs 208 / 104 = 2 boxes of dryer sheets. Each box costs $5.50 and she used 2 boxes so she now saves 5.50 * 2 = $11.00 by not buying dryer sheets. The answer is 11.
