A: The first 5 days cost 5 * 100 = $500. He gets 10 - 5 = 5 days on discount. He paid 5 * 60 = $300 at the discounted rate. So in total he pays 500 + 300 = $800. The answer is 800.
Question: Cid owns a mechanic shop, he charges $20 for an oil change, $30 for a repair, and $5 for a car wash. How much money did he earn if he changed the oil of 5 cars, repaired 10 cars, and washed 15 cars?

Q: A school cafeteria uses ground mince to cook lasagnas and cottage pies. They make 100 lasagnas, which use 2 pounds of ground mince each, and cottage pies, which use 3 pounds of ground mince each. If the cafeteria has used 500 pounds of ground mince in total, how many cottage pies did they make?
A: The cafeteria used 100 lasagnas * 2 pounds of ground mince = 200 pounds of ground mince for the lasagnas. This means they used 500 pounds of ground mince in total 200 pounds of ground mince for the lasagnas = 300 pounds of ground mince for the cottage pies. So they must have made 300 pounds of ground mince for the cottage pies / 3 pounds of ground mince per cottage pie = 100 cottage pies. The answer is 100.
Question: Sophie does 4 loads of laundry a week and uses 1 dryer sheet per load. A box of dryer sheets costs $5.50 and has 104 dryer sheets in a box. On her birthday, she was given wool dryer balls to use instead of dryer sheets. How much money does she save in a year not buying dryer sheets?
Answer: She does 4 loads of laundry a week and used 1 dryer sheet per load for a total of 4 * 1 = 4 dryer sheets in a week. She used 4 dryer sheets per week for 52 weeks for a total of 4 * 52 = 208 dryer sheets. Her box of dryer sheets has 104 sheets so she needs 208 / 104 = 2 boxes of dryer sheets. Each box costs $5.50 and she used 2 boxes so she now saves 5.50 * 2 = $11.00 by not buying dryer sheets. The answer is 11.
Q: A highway is being extended from its current length of 200 miles up to 650 miles. 50 miles are built on the first day, and three times this amount are built on the second day. How many miles still need to be added to the highway to finish extending it?
A:
The length of the highway that needs to be constructed is 650 200 = 450 miles. After the first day, there are still 450 50 = 400 miles that need to be constructed. On the second day, 50 miles * 3 = 150 miles are added to the highway. This means that 400 150 = 250 miles still need to be added to the highway. The answer is 250.
