Eight pounds of peanuts cost $24.00. Six pounds of walnuts cost half as much.

Which is more expensive and by how much?

peanuts are more expensive by $1.00.

Step-by-step explanation:

∵ The cost of eight pounds of peanuts = $24.00

∴ The cost of one pound of peanuts =

                                                           = $3.00 per pound

∵ The cost of six pounds of walnuts half as much =

                                                                               = $12.00

∴ the cost of one pound of walnuts =

                                                           = $2.00 per pound

Difference in the cost per pound = $3.00 - $2.00 = $1.00

Therefore, peanuts are more expensive by $1.00.
