The formula to find the unit price of one is (TOTAL PRICE)/(QUANTITY)
———————————————————————————————————————————
Brand A = 36 spoons for 1.54 dollars so divide 1.54 by 36 which rounded is 0.04 cents
Brand B = 48 spoons for 1.66 dollars so divide 1.66 by 48 which rounded is 0.03 cents
Since Brand B has a lower unit price than Brand A, Brand B would be the better buy.
