[Question]Leah earned $28 working odd jobs around the neighborhood. She spent a seventh of it on a milkshake and put half of the rest in her savings account. She left the remaining money in her wallet. Her dog got ahold of her wallet and shredded all the money inside but $1. How many dollars did Leah lose?
[Answer]Leah spent 28 / 7 = $4 on a milkshake. She had 28 - 4 = $24 left. She put half in her savings account and half in her wallet, so she had 24 / 2 = $12 in her wallet. Her dog shredded all the money in her wallet but $1, so Leah lost 12 - 1 = $11. The answer is 11.
Q: For Roger's phone to function optimally, he can have a maximum of 50 apps on his phone. However, the recommended number of apps is 35. If Roger has twice the recommended number of apps, how many apps must he delete for his phone to function optimally again?

Question: Nancy can hula hoop for 10 minutes. Casey can hula hoop 3 minutes less than Nancy. Morgan can hula hoop three times as long as Casey. How long can Morgan hula hoop?
Answer: Casey can hula hoop 3 minutes less than Nancy so she can hula hoop for 10 - 3 = 7 minutes. Morgan can hula hoop three times as long as Casey, who can hula hoop for 7 minutes, so she can hula hoop for 3 * 7 = 21 minutes. The answer is 21.
[Question]Luke takes a 70-minute bus to work every day. His coworker Paula takes 3/5 of this time to arrive by bus at work. If Luke takes a bike ride back home every day, 5 times slower than the bus, and Paula takes the bus back home, calculate the total amount of time, in minutes, they take traveling from home to work and back each day.
[Answer]When Luke takes the 70 - minute bus to work, his coworker Paula takes 3 / 5 * 70 = 42 minutes to travel from home to work. From work to home, Paula spends the same amount of time she spent going to work, giving a total of 42 + 42 = 84 minutes in a day traveling. From work to home, while riding the bike, Luke spends 5 * 70 = 350 minutes on the road. The total time Luke takes to travel from home to work and back is 350 + 70 = 420 minutes. Together, Luke and Paula takes 420 + 84 = 504 minutes. The answer is 504.
Q: Sarah bought 12 lollipops filled with caramel for a total of 3 dollars. She offered to share one-quarter of the lollipops with her friend, Julie, but Julie insisted on reimbursing Sarah for the cost of the lollipops shared. How much money, in cents, did Julie give Sarah to pay for the shared lollipops?
A: Since one dollar is 100 cents, then 3 dollars is 3 * 100 = 300 cents. The cost for one lollipop is 300 / 12 = 25 cents. One - quarter of the lollipops is 12 / 4 = 3 lollipops. At 25 cents per lollypop, 3 lolly's cost 3 * 25 = 75 cents. The answer is 75.
Question: Jenny wants to heat a dish for dinner. It needs to be at 100 degrees before it is ready to eat. It is 20 degrees when she places it in the oven, and it heats up 5 degrees every minute. How many minutes will it take to be ready?
Answer:
To determine this, we must first figure out the required change in temperature. To do this, we perform 100 - 20 = 80 degrees of required temperature change. Next, we divide this amount by the rate of change per minute, performing 80 / 5 = 16 minutes of cooking time. The answer is 16.
