Answer the following question.
Walter works 5 days a week in a fast-food chain and earns $5 per hour. Since he is a working student, he can only work 4 hours a day and allocates 3/4 of his weekly earning for his schooling. How much does he allocate for school?
Step-by-step reasoning process: Walter's daily earning is $5 x 4 = $20. So he earns $20 x 5 = $100 per week. Therefore, he allocates $100 x 3 / 4 = $75 for his school.
The answer is 75.

Answer the following question.
On a weekend road trip, the Jensen family drove 210 miles on highways, where their car gets 35 miles for each gallon of gas and 54 miles on city streets where their car gets 18 miles for each gallon. How many gallons of gas did they use?
Step-by-step reasoning process: On highways, the Jensen family used 210 miles / 35 miles / gallon = 6 gallons of gas. On city streets, the Jensen family used 54 miles / 18 miles / gallon = 3 gallons of gas. Total, the Jensen family used 6 gallons + 3 gallons = 9 gallons of gas.
The answer is 9.

Answer the following question.
There are 20 sandcastles on Mark's beach, each with 10 towers. On Jeff's beach, there are three times as many castles as on Mark's beach, each with 5 towers. What is the combined total number of sandcastles and towers on Mark's and Jeff's beaches?
Step-by-step reasoning process: The total number of towers at Mark's beach is 20 * 10 = 200 towers. There are 200 + 20 = 220 sandcastles and towers on Mark's beach. Jeff's beach has 3 * 20 = 60 sandcastles, three times as many as the number of sandcastles in Mark's beach. The number of towers in each of the sandcastles on Jeff's beach is 1 / 2 * 10 = 5. Since each sandcastle has 5 towers on Jeff's beach, there are 5 * 60 = 300 towers. In total, on Jeff's beach, there are 300 + 60 = 360 towers and sandcastles. Altogether, 360 + 220 = 580 sandcastles and towers can be found on their beaches.
The answer is 580.
