Step-by-step explanation:
Hello!
To compare different prices of several brands of a product the best is to express the price for the same quantities of product.
Since the three options are original in 300g, 450g and 600g, I'll express all prices on a base of 100g of product. You can use simple rule of three for this:
Option 1
300g cost $3.89
100g cost
Option 2
450g cost $ 4.77
100g cost
Option 3
600g cost $ 6.59
100g cost
So:
Option 1: $1.296/ 100g
Option 2: $1.06/100g
Option 3: $1.098/100g
The cheapest option is number 2
I hope this helps!
