Question: Jake has $5000. He spends $2800 on a new motorcycle, and then spends half of what's left on a concert ticket. Jake then loses a fourth of what he has left. How much money does he have left?
Answer: Step-by-step reasoning process: Jake has 5000 - 2800 = $2200 left. Jake has 2200 / 2 = $1100. Jake loses 1100 / 4 = $275. Jake has 1100 - 275 = $825 left.
So the answer is 825.

Question: A farmer has twice as many pigs as cows, and 4 more cows than goats. If the farmer has 56 animals total, how many goats does he have?
Answer: Step-by-step reasoning process: Let x be the number of goats. Cows:4 + x. Pigs:2(4 + x) = 8 + 2x. Total:x + 4 + x + 8 + 2x = 56. 4x + 12 = 56. 4x = 44. x = 11 goats.
So the answer is 11.

Question: Uki owns a bakery. She sells cupcakes at $1.50 each, cookies at $2 per packet, and biscuits at $1 per packet. In a day, she can bake an average of twenty cupcakes, ten packets of cookies, and twenty packets of biscuits. How much will be her total earnings for five days?
Answer: Step-by-step reasoning process: Uki earns 20 x $1.50 = $30 in selling 20 cupcakes. She earns 10 x $2 = $20 for selling 10 packets of cookies,. Additionally, she earns another 20 x $1 = $20 for selling twenty packets of biscuits. Thus, in a day, she earns an average of $30 + $20 + $20 = $70.                                    Therefore, for five days, Uki earns 5 x $70 = $350. ".
So the answer is 350.

Question: Betty is saving money for a new wallet which costs $100. Betty has only half of the money she needs. Her parents decided to give her $15 for that purpose, and her grandparents twice as much as her parents. How much more money does Betty need to buy the wallet?
Answer:
Step-by-step reasoning process: In the beginning, Betty has only 100 / 2 = $50. Betty's grandparents gave her 15 * 2 = $30. This means, Betty needs 100 - 50 - 30 - 15 = $5 more.
So the answer is 5.
