Answer:

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 \frac{100*3.89}{300} = $1.296

Option 2

450g cost $ 4.77

100g cost \frac{100*4.77}{450}= $1.06

Option 3

600g cost $ 6.59

100g cost \frac{100*6.59}{600}= 1.098

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!
