Question

A sale on dog food that costs $10 a bag says buy 1, get one `1/2` off. What is the true percent discount on the dog food?

Answer 1

`25%`

Explanation:

`2` bags is `$20` normally but you're getting the second one for half off.

So you are paying `$15` for two bags.

`15/20 =0.75`

`0.75 xx 100% = 75%`

So `25%` is the discount.
