Angus has $20 worth of tokens less than Elsa has. If Elsa has 60 tokens and each token is worth $4, how many tokens does Angus have?
Let's think: If each token is worth $4, then $20 worth of tokens is $20 / $4 = 5 tokens. Angus has 5 tokens less than Elsa who has 60 so Angus has 60 - 5 = 55 tokens.. The answer is: 55.

Tas and his friends put up a t-shirt for sale. They ended up selling 200 t-shirts in 25 minutes. Half of the shirts were black and cost $30, while the other half were white and cost $25. How much money did they make per minute during the sale?
Let's think: The total revenue from black shirts was 100 * $30 = $3000. The total revenue from white shirts was 100 * $25 = $2500. The total revenue from all shirts sold was $3000 + $2500 = $5500. Tas and his friends ended up making $5500 / 25 minutes = $220 per minute.. The answer is: 220.

Peter has 20 books. He has read 40% of them. His brother has read 10% of them. How many more of these books has Peter read than his brother?
Let's think: Peter has read 8 of these books because 20 x .4 = 8. His brother has read 2 of these books because 20 x .1 = 2. Peter has read 6 more books than his brother because 8 - 2 = 6.. The answer is: 6.

The town is having a race to see who can run around the town square 7 times the fastest. The town square is 3/4 of a mile long. The winner finishes the race in 42 minutes. Last year's winner finished in 47.25 minutes. How many minutes on average faster did this year's winner run one mile of the race compared to last year?
Let's think:
The race is 5.25 miles long because 7 x .75 = 5.25. They ran a mile in 8 minutes because 42 / 5.25 = 8. Last year's winner ran a mile in 9 minutes because 47.25 / 5.25 = 9. They ran 1 minute faster per mile compared to last year's winner.. The answer is: 1.
