Question

Which is better to buy 2 ounce for 0.50 or 3 ounce for 0.78

Answer 1

hello

let's simply calculate both and compare

1.

if two ounce cost $0.50, let's divide 0.5 by 2 to know the cost of each ounce

`1\text{ounce}=(0.50)/(2)=0.25`

2.

if three ounce cost $0.78, what is the cost of 1 ounce?

let's simply divide 0.78 by 3

`1\text{ounce}=(0.78)/(3)=0.26`

the first option is better because $0.25 an ounce is better than $0.26 per ounce
