Question

Product A is a 12-ounce bottle of generic popcorn oil that sells for $1.39.

Product B is a 24-ounce popcorn oil bottle that costs $2.79.

Which is the better buy?

Answer 1

product A because if you multiply the price by 2, you get $2.78 which saves a whole wopping .01 cent haha

Answer 2

Product A :
12/1.39 = 1/x
cross multiply
12x = 1.39
x = 1.39/12
x = .115

Product B :
24/2.79 = 1/x
cross multiply
24x = 2.79
x = 2.79/24
x = .116

Product A is cheaper.....not by much :)
