Annie spends 4 * 8 = 32 dollars on hamburgers. Annie spends 3 * 6 = 18 dollars on milkshakes. Annie spends 32 + 18 = 50 dollars on hamburgers and milkshakes. Annie has 120 - 50 = 70 dollars left.
The answer: 70

Reasoning and answer: First convert 90 minutes to hours: 90 minutes / 60 minutes / hours = 1.5 hours. In 1 hour, I run 12 miles / 1.5 hours = 8 miles / hour.
The answer: 8
What was the question?
Question: I run 12 miles in 90 minutes. What is my average speed in miles per hour?


The number of adults present is 250 – 188 = 62 adults. The revenue generated by adults is 62 * 6 = $372. The revenue generated by children is 188 * 4 = $752. So the total ticket revenue is 372 + 752 = $1124.
The answer: 1124
