Reasoning and answer: There are 7 people on the bus after the first stop. There are 7 + 5 - 3 = 9 people on the bus after the second stop. There are 9 + 4 - 2 = 11 people on the bus after the third stop. 11 passengers are now on the bus.
The answer: 11
What was the question?
Question: The bus started its route. At its first stop, 7 people got on. At the second stop, 3 people got off, and 5 people got on. At the third stop, 2 people got off, and 4 people got on. How many passengers are now on the bus?
Jack earned from the brownies $3 per brownie * 4 brownies = $12. Jack earned from the lemon squares $2 per square * 5 squares = $10. He still needs to earn $50 - $12 - $10 = $28. He sells cookies for $4 each, so Jack still needs to sell $28 / $4 = 7 cookies.
The answer: 7
Reverse engineering the question: Jack is running a bake sale to help pay for his basketball team's uniforms. He's already sold 4 brownies for $3 each and 5 lemon squares for $2 each. If Jack's goal is to make $50 and he sells cookies for $4 each, how many cookies does he need to sell to reach his goal?
Reasoning and answer: Since Governor Sandoval gave 12 commencement addresses, twice the number that Governor Hawkins gave, Governor Hawkins gave 12 / 2 = 6 commencement addresses. The two of them gave 6 + 12 = 18 commencement addresses in total. Governor Sloan gave ten more commencement addresses than Governor Sandoval, a total of 12 + 10 = 22 commencement addresses. The three of them gave 22 + 18 = 40 commencement addresses.
The answer: 40
What was the question?
Question: In her first term, Governor Sandoval gave twice as many commencement addresses as Governor Hawkins. Governor Sloan gave ten more commencement addresses than Governor Sandoval in the same amount of time. If Governor Sandoval gave 12 commencement addresses, how many commencement addresses did the three of them give altogether?
The second flight had 20 * 2 = 40 steps. The third had 40 - 10 = 30 steps. So in total, he climbed 20 + 40 + 30 = 90 steps. So he climbed 90 * .5 = 45 feet.
The answer: 45
Reverse engineering the question: John climbs 3 staircases. The first staircase has 20 steps. The next has twice as many steps as the first. The final staircase has 10 fewer steps than the second one. Each step is 0.5 feet. How many feet did he climb?
Reasoning and answer: After 30 days, there will be enough food left to sustain 300 people for 90 days 30 days = 60 days. After the 100 people leave, there will be 300 - 100 = 200 people left. The 200 people will eat 200 / 300 = 2 / 3 as much food as the original group of people in the castle. The 60 days' worth of food will last this smaller group for 60 days / (2 / 3) = 90 more days.
The answer: 90
What was the question?
Question: There are enough provisions in a castle to feed 300 people for 90 days. After 30 days, 100 people leave the castle. How many more days are left until all the food runs out?
Reasoning and answer: During the race, there were five ads, lasting 3 minutes each, so in total, they lasted 5 * 3 = 15 minutes. So the total cost of these ads was 15 * 4000 = $60000.
The answer: 60000
What was the question?
Question:
During a race transmitted on television, five advertisements were shown, lasting 3 minutes each. One minute of advertising costs $4000. What was the cost of transmitting these advertisements during the race?
