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? Let's be accurate as possible.

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: 6.
