Q: Jerusha earned 4 times as much money as Lottie. Together they earned $85. How many dollars did Jerusha earn? Use L to represent Lottie's earnings.
A: L = Lottie's earnings. Jerusha's earnings = 4L. L + 4L = 85. L = 85 / 5. L = 17 so Jerusha earned 4L = 4(17) = 68. Jerusha earned $68. The answer is 68.
Question: Ariel is collecting fish. She has 45 fish. 2/3 are male. How many female fish does she have?

[Question]To earn an airplane pilot certificate, Sangita is required to fly 1,500 hours. She has already completed 50 hours of day flying, 9 hours of night flying, and 121 hours flying cross-country. To meet her goal in exactly 6 months, how many hours per month must Sangita fly?
[Answer]Sangita has already flown for a total of 50 hours + 9 hours + 121 hours = 180 hours. The flight time she has remaining is 1500 hours - 180 hours = 1320 hours. Sangita's monthly target must therefore be 1320 hours / 6 months = 220 hours / month. The answer is 220.
Q: Mark is running for an election and wins 70% of the votes in an area with 100,000 voters. He got twice as many total votes in the remaining area. How many votes did he get in total?
A: He got 100,000 * .7 = 70,000 votes from the first area. He got 70,000 * 2 = 140,000 votes in the remaining areas. So in total he got 140,000 + 70,000 = 210,000 votes. The answer is 210000.
Question: A bicycle store is running a promotion. Every time a customer buys a bicycle, they will receive 2 bike clamps free with it. If the store sells 19 bikes in the morning and 27 bikes in the afternoon, how many bike clamps has the store given to customers?
Answer: In the morning, the store gives away 19 bikes * 2 bike clamps = 38 bike clamps. In the afternoon, they give away 27 bikes * 2 bike clamps = 54 bike clamps. So in total, the store has given away 38 + 54 = 92 bike clamps. The answer is 92.
Q: Jim starts with $80 in his investment portfolio. After 1 year it grows by 15%. He then adds another $28 to his portfolio. After 1 more year the combined portfolio grows by 10%. What is his final portfolio worth after 2 years from when he started?
A:
After 1 year Jim has gained $80 * 0.15 = $12. Therefore, after 1 year his portfolio has grown to $80 + $12 = $92. He then adds $28 to this total, so his new portfolio total is $92 + $28 = $120 at the beginning of year 2. Next, this total grows by 10%, so he gains $120 * 0.10 = $12 across year 2. Thus, after year 2, his portfolio is worth $120 + $12 = $132. The answer is 132.
