Question: The news announced a $0.4 oil price rollback this Friday. Mr. Deane decided to only fill his gas tank with 10 liters of gas today and then another 25 liters on Friday. If the cost per liter of gas is $1.4 today, how much will Mr. Deane spend for his 35 liters of gas?
Answer: Mr. Deane will spend $1.4 / liter x 10 liters = $14 for the 10 liters of gas today. The price of the gas per liter on Friday will be $1.4 / liter - $0.4 / liter = $1 / liter. So, he will spend $1 / liter x 25 liters = $25 for the 25 liters of gas on Friday. Thus, Mr. Deane will spend a total of $14 + $25 = $39 for the 35 liters of gas. The answer is 39.
[Question]Mandy is ten years older than Jackson. Adele is 3/4 as old as Jackson. What's the total of their ages 10 years from now If Jackson is 20 years old now?
[Answer]In ten years, Jackson will be 20 + 10 = 30 years old. If Jackson is 20 now, Mandy is 20 + 10 = 30 years old. Ten years from now, Mandy will be 30 + 10 = 40 years old. The combined age of Jackson and Mandy ten years from now is 30 + 40 = 70 years. Adele is 3 / 4 times as old as Jackson, meaning she is 3 / 4 * 20 = 15 years old. Adele's age will be 10 + 15 = 25 years old ten years from now. Altogether, Mandy, Jackson, and Adele will have a total of 25 + 70 = 95 years. The answer is 95.
Q: Vikki worked 42 hours in one week. Her hourly pay rate is $10. From her weekly earnings, 20% is deducted as tax, 5% is deducted as insurance cover, and $5 is deducted for union dues. How much money, in dollars, does Vikki take home after deductions?
A: Vikki earnt 10 × $42 = $420 in one week. She then gets taxed $420 × 0.2 = $84. She also loses $420 × 0.05 = $21 due to insurance. Vikki also pays $5 in union dues. In total Vikki loses $84 + $21 + $5 = $110 because of deductions. Her final total pay after deductions is $420 - $110 = $310. The answer is 310.
Question: Jordan's dog, Max, was born on the same day that Luka turned 4 years old. Luka is exactly 2 years older than is Aubrey. On Aubrey's 8th birthday, how many years old was Jordan's dog, Max?
Answer: If Luka is exactly 2 years older than is Aubrey, then on Aubrey's 8th birthday, Luka was 8 + 2 = 10 years old. If Jordan's dog, Max, was born on the same day that Luka turned 4 years old, then when Luka was 10 years old, Max was 10 - 4 = 6 years old. The answer is 6.
[Question]Bill and Jean are both cleaning out their garages. Bill makes a certain number of trips to the dump and Jean makes that many trips plus 6. If they make 40 trips total, how many trips does Jean make?
[Answer]Let b be the number of trips Bill makes and j be the number Jean makes. We know that b + j = 40, and j = b + 6. Substituting the first equation into the second equation, we get b + b + 6 = 40. Combining like terms, we get 2b + 6 = 40. Subtracting 6 from both sides, we get 2b = 34. Dividing both sides by 2, we get b = 17. Substituting that value back into j = b + 6, we get j = 17 + 6 = 23. The answer is 23.
[Question]Susie babysits every day for 3 hours a day at the rate of $10 per hour. She spent 3/10 of the money she earned from last week to buy a make-up set. She then spent 2/5 of her money on her skincare products. How much is left from her earnings last week, in dollars?
[Answer]
Susie earned $10 x 3 = $30 per day. Last week, she earned a total of $30 x 7 = $210. She spent $210 x 3 / 10 = $63 on make - up. While she spent $210 x 2 / 5 = $84 on her skincare products. Thus, she spent a total of $63 + $84 = $147 from her earnings. Therefore, Susie is left with $210 - $147 = $63 from her earnings last week. The answer is 63.
