Question

The cost of one pen when pens are priced at 5 for p dollars

I really need help on this

Answer 1

5 dollar for one pen

Answer 2

$1

Explanation:

If 5 pens = $p, then 1 pen = $p/5.

But because 5 pens = $p, it would be the same thing as 5 = p because you just take off the labels.

So p = 5 and one pen would be:

$p/5 = 1

5/5 = 1

1 = 1
