Question

Elsie bought 3.00 pounds of pecans for $9.60. Her friend buys 4.50 pounds of walnuts for $15.75. Which is more expensive per pound? By how much?

Answer 1

Divide 9.60 by 3, and 15.75 by 4.50
The bigger number will be the most expensive and subtract the bigger quotient by the smaller and you’ll get the difference.
