Which is a better by 3 lb of pears for $3.87 or 5 lb of pears for $6.65

Shtirlitz [24]

Since 3lb pears is $3.87 lets say that every 1lb of pears costs $1.30.
say if you were to buy 2lb on-top of the 3lb it would cost $2.60 extra, causing the total price to be around $6.50 (rounded up)

so since 5lb is $6.65, i believe that the 3lb of pears is the better buy.
