James buys 3 packs of candy. He pays with a $20 bill and gets $11 change. How much did each pack of candy cost? Give the rationale and then the answer.
Let's think step by step. The candy cost 20 - 11 = $9. So he pays 9 / 3 = $3 per candy.. The answer is: 3.

Liam and Claire picked and sold oranges to save for their mother's birthday gift. Liam picked 40 oranges and sold them at $2.50 for 2 while Claire picked 30 oranges and sold them at $1.20 each. If all of their oranges were sold, how much are they going to save for their mother's birthday gift? Give the rationale and then the answer.
Let's think step by step. Liam sold 40 / 2 = 20 sets of oranges that cost $2.50 for each set. So, Liam earned $2.50 x 20 = $50. Claire earned $1.20 x 30 = $36. Thus, they were able to save $50 + $36 = $86 for their mother's birthday gift.. The answer is: 86.

Janet buys 3 pounds of broccoli for $4 a pound, 3 oranges for $0.75 each, a cabbage for $3.75, a pound of bacon for $3, and two pounds of chicken for $3 a pound. What percentage of her grocery budget did she spend on meat, rounded to the nearest percent? Give the rationale and then the answer.
Let's think step by step. First find the total cost of the broccoli: 3 pounds * $4 / pound = $12. Then find the total cost of the oranges: 3 oranges * $0.75 / orange = $2.25. Then find the total cost of the vegetables: $12 + $2.25 + $3.75 = $18. Then find the total cost of the chicken: $3 / pound * 2 pounds = $6. Then add the cost of the bacon to find the total cost of the meat: $6 + $3 = $9. Then add the cost of the meat and vegetables to find the total cost of the groceries: $9 + $18 = $27. Then divide the cost of the meat by the total grocery bill and multiply by 100% to express the answer as a percentage: $9 / $27 * 100% = 33.333%, which rounds down to 33%.. The answer is: 33.
