[Question]Lauren wanted to make burgers and fries for dinner. She needed a few things from the grocery store and bought the following: 2 pounds of hamburger meat that was on sale for $3.50 a pound. 1 pack of hamburger buns for $1.50. A head of lettuce for $1.00 and a large 1.5-pound tomato that was priced at $2.00 per pound. She also needed a jar of pickles that cost $2.50 and she had a $1.00 off coupon for that item. How much change would Lauren get back if she paid with a $20 bill?
[Answer]She bought 2 pounds of hamburger meat at $3.50 per pound so 2 * 3.50 = $7.00. The tomato weighed 1.5 pounds and cost $2.00 per pound so 1.5 * 2 = $3.00. When you add up all her items she spent 7 + 1.50 + 1 + 3 + 2.50 = $15.00. Her items added up to $15.00 and she had a $1.00 coupon off pickles so 15 - 1 = $14.00. She paid with a $20.00 bill so 20 - 14 = $6.00 in change. The answer is 6.

[Question]Jame gets 20 singing lessons. He gets the first lesson free and after the first 10 paid lessons he only needs to pay for every other lesson. Each lesson is $5. His uncle pays for half. How much does James pay?
[Answer]The first lesson is free. The lessons 2 to 11 cost 10 * $5 = $50. He then had 9 remaining lessons where he had to pay for every other one. So he pays for lessons 13,15,17&19 = 4 lessons. Those lessons cost 4 * $5 = $20. So in total, the cost was $50 + $20 = $70. So he paid $70 / 2 = $35. The answer is 35.

[Question]Alan bought a $2000 phone online. John bought it 2% more expensive in a local store. How much did John spend on his phone?
[Answer]The difference in price is 2% * 2000 = $40. So, the price of John's phone is 2000 + 40 = $2040. The answer is 2040.
