Question

A store sells a 28oz. Bottle of shampoo for $1.96. It also sells a 22 oz. bottle of shampoo for $1.32. Which bottle is the better deal?

Answer 1

Answer:

22 oz. bottle

Step-by-step explanation:

To be able to find which of the bottles of shampoo has a better deal, we first need to find out how much they cost per ounce.

We take the price and divide it to the number of ounces in the bottle.

For the 28oz bottle:

$\dfrac{1.96}{28}= 0.07 per ounce.$

For the 22oz bottle:

$\dfrac{1.32}{22}= 0.06 per ounce.$

Now that we have the value for a single ounce from each bottle, we can simply see that we get more from the 22oz bottle than the 28oz bottle.

To explain it further, let's try to find out how much the price will be if the 22oz bottle was a 28oz bottle.

To get the value we need to multiply the price per ounce by 28 to find out if it is a better deal.

0.06 x 28 = $1.68

Even if the 22oz bottle was a 28oz bottle, we would still get a better deal from that brand.
