Question: A school canteen sells a sandwich at $2, a hamburger at $2, one stick of hotdog at $1, and a can of fruit juice at $2 each can. Selene buys three sandwiches and a can of fruit juice. Tanya buys two hamburgers and two cans of fruit juice. How much do Selene and Tanya spend together?
Answer: Step-by-step reasoning process: Three sandwiches cost 3 x $2 = $6. So, Selene spends $6 + $2 = $8. Two hamburgers cost 2 x $2 = $4. Two cans of fruit juice cost 2 x $2 = $4. Thus, Tanyah spends $4 + $4 = $8. Therefore, Selene and Tanya spend $8 + $8 = $16.
So the answer is 16.

Question: Nancy's ex owes her child support. He's supposed to pay 30% of his income each year. For 3 years, he made $30,000/year, then he got a 20% raise for the next four years. If he's only ever paid $1,200, how much does he owe her?
Answer: Step-by-step reasoning process: First find how much money the ex made during the first 3 years by multiplying his annual earnings by the number of years: 3 years * $30,000 / year = $90,000 / . Then find how much his raise was by multiplying his salary by the percentage raise: $30,000 / year * 20% = $6,000 / year. Then add the raise to his original salary to find his new salary: $6,000 / year + $30,000 / year = $36,000 / year. Then find how much he made working at the new salary by multiplying it by the 4 years he worked: 4 years * $36,000 / year = $144,000. Add his earnings from the three years and the four years to find his total earnings: $144,000 + $90,000 = $234,000. Now multiply his total earnings by 30% to find how much he was supposed to pay: $234,000 * 30% = $70,200. Now subtract the amount he paid from this number to find how much he owes: $70,200 - $1,200 = $69,000.
So the answer is 69000.

Question: The Early Bird Dinner offered dinner meals at half off the menu price if you eat between 2-4 pm. Curtis ordered the Salisbury Steak that costs $16.00 and Rob ordered the Chicken Fried Steak at $18.00. If they ate at 3 pm, what was the cost of their total bill?
Answer: Step-by-step reasoning process: Curtis had the Salisbury steak for $16.00 and Rob had the Chicken Fried Steak at $18.00 so their meal cost 16 + 18 = $34.00. They ate 3 pm so their meal is half off so their meal cost 34 / 2 = $17.00.
So the answer is 17.

Question: Mr. Grey's house was worth $100,000. He sold the house to Mr. Brown at a profit of 10%. After one year, Mr. Brown sold the house to his other friend with a 10% loss. How much was Mr. Brown's selling price?
Answer:
Step-by-step reasoning process: Mr. Grey had a $100 000 x 10 / 100 = $10,000 profit. So, Mr. Grey sold the house to Mr. Brown for $100 000 + $10 000 = $110,000. Mr. Brown sold the house $110 000 x 10 / 100 = $11,000 less than its purchased price. Thus, Mr. Brown sold it for $110 000 - $11 000 = $99,000 to his friend.
So the answer is 99000.
