What (perhaps surprising) simple generalization about the cost of things might we make based on the table and graph of exercise 21? Does the comparative lack of spread in price surprise you?

In visiting stores, we find the following prices for various things. Broccoli crowns cost $2.89 per pound. Soft drinks cost $2.00 per two-liter bottle. (A liter is 0.001 m³.) A new automobile weighs 2.50 × 10³ lbf and costs $1.50 × 10⁴. A dozen oranges, each of which is 0.06 m in diameter, costs $2.05. A 1.5 lb package of chicken thighs costs $5.35. A dictionary weighs 5.00 pounds and costs $20. A refrigerator weighs 200. lbf and costs $900. Assume that one cubic meter of any solid object or liquid weighs 1.00 × 10⁴ N.
