For part (a), $9.70 is divided by 2.5 (pounds) to result to $3.88 per pound. ($8.55 - $3.88 = $4.67), which is how much less per pound peanuts cost than almonds. For part (b), multiplying $8.55 by 1.4 (pounds) gives $11.97, which, when $9.70 is subtracted from this to compare it to the cost of the peanuts, leaves $2.27. This is how much more the almonds cost to purchase than the peanuts.
