Question. 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?
Answer. 33
What step-by-step reasoning justifies that answer?
Reasoning: 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%.
