Re: averages
Hi william15969;
Welcome to the forum! It is easy do, form the equation:
where x is the price of the missing pair of shoes.
Can you solve that for x? Give it a try!
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
