Question

Suppose a grocery store is having a sale on shredded cheese. A small bag that holds 8 ounces is sold for $2. A large bag that holds 2 kilograms is sold for $16. How do you know which is a better deal?

Answer 1

Answer:

2 kg for $16 is the better deal

Step-by-step explanation:

First we need to bring in one unit

We know

1 kg = 35 oz

So, we can say,

$2 for 8 oz (ounce)

and

$16 for 2*35 = 70 oz (ounce)

Now we have to find cost per ounce for each and see which is the better deal.

First one:

$2 for 8 ounce means 2/8 = $0.25 per ounce

Second one:

$16 for 70 ounce means 16/70 = $0.23 per ounce

So,

2 kg for $16 is the better deal.
