Question: Frank's laundry detergent is double concentrated and will wash 80 loads of laundry. His detergent is usually $25.00 a bottle but they're having a sale. If he buys 2 bottles, both bottles will drop to $20.00 a bottle. How much does he spend, in cents, per load of laundry, if he buys 2 bottles of detergent?
Answer: Step-by-step reasoning process: If he buys 2 bottles, the price drops to $20.00 per bottle so they cost 2 * 20 = $40.00. He can get 80 loads of laundry per bottle and he bought 2 bottles so that's 80 * 2 = 160 loads of laundry. The detergent cost $40.00 and he will be able to wash 160 loads of laundry so each load costs 40 / 160 = $0.25.
So the answer is 25.

Question: Maiya has two sisters. The first sister is twice as old as Maiya. The first sister is 1 year younger than Maiya. Their average age is 5. How old is Maiya?
Answer: Step-by-step reasoning process: Their total age is 15 because 3 x 5 = 15. 15 - X - 2X - (X - 1) is equivalent to 16 = 4X. Maiya is 4 years old because 16 / 4 = 4.
So the answer is 4.

Question: A mother duck as 8 ducklings. The first 3 ducklings find 5 snails each. Another 3 ducklings find 9 snails each, and the remaining ducklings each find half the number of snails that mother duck finds. If mother duck finds tree times the total number of snails as the first 2 groups of ducklings, how many snails does the family of ducks have collectively?
Answer: Step-by-step reasoning process: The first 3 ducklings find 3 x 5 = 15 snails. The next 3 ducklings find 3 x 9 = 27 snails. They find a total of 15 + 27 = 42 snails. Mother duck finds 42 x 3 = 126 snails. The last group has 8 - 3 - 3 = 2 ducklings. They find 126 / 2 = 63 snails each. The family of ducks found a total of 42 + 126 + 63 + 63 = 294 snails.
So the answer is 294.

Question: Roe saved $10 per month from January to July and saved $15 per month from August to November. How much should she save in December so she will have a total savings of $150 in the year?
Answer:
Step-by-step reasoning process: Since there are 7 months from January to July, then Roe's savings for those months sum up to $10 x 7 = $70. Since there are 4 months from August to November, then her savings for those months sum up to $15 x 4 = $60. Her total savings from January to November is $70 + $60 = $130. Therefore, she needs to save $150 - $130 = $20 in December.
So the answer is 20.
