Answer:
Jane spends $6/lb for the vegetables.
Explanation:
Multiply the number of pounds of fruit she bought and the cost for each pound. That would mean 4 times 5 which equals 20. Subtract 20 from 50 because that shows you how much money she had left. Divide the number of money she has left with the amount of pounds she bought. 30 divided by 5 gives you your final answer of $6 per pound.
