Question: The difference in ages between Richard and Hurley is 20. If Hurley is 14 years old, what are their combined ages 40 years from now?
Answer: If Hurley is 14 years old, and the difference in ages between Richard and Hurley is 20, Richard is 20 + 14 = 34. Forty years from now, Hurley will be 14 + 40 = 54 years old. Richard will be 40 + 34 = 74 years forty years from now. Their combined ages forty years from now will be 74 + 54 = 128 years. The answer is 128.

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: Five coworkers were talking during the lunch break. Roger, the oldest one, said that he has the same amount of experience in years as all four of the others combined and that his retirement should come when he accumulates 50 years of experience. Peter said that when he came to the company his daughter was 7 years old, and now she is 19 years old. Tom then said he has twice as many years of experience as Robert. Robert said that he has 4 years of experience less than Peter but 2 more years of experience than Mike. How many more years does Roger have to work before he retires?
Answer: Peter has 19 – 7 = 12 years of experience. Robert has 12 – 4 = 8 years of experience. Mike has 8 – 2 = 6 years of experience. Tom has 2 * 8 = 16 years of experience. Roger has 12 + 8 + 6 + 16 = 42 years of experience. Roger has to work another 50 – 42 = 8 years before he retires. The answer is 8.

Question: Mitch made 20 macarons. Joshua made 6 more macarons than Mitch but half as many macarons as Miles. Renz made 1 fewer than 3/4 as many macarons as Miles. If they will combine their macarons to give them to the kids on the street, how many kids would receive 2 macarons each?
Answer:
Joshua made 20 + 6 = 26 macarons. Miles made 26 x 2 = 52 macarons. Three - fourths of Miles' macarons is 52 x 3 / 4 = 39. So Renz made 39 - 1 = 38 macarons. The four of them have a total of 20 + 26 + 52 + 38 = 136 macarons combined. Thus, 136 / 2 = 68 kids would receive 2 macarons each. The answer is 68.
