How To Figure Gross With a Certain Net Figure
May 21, 2009
OK math Guru's, I'm going to give you the question and the answer,
what I need from you is the easiest way to GET TO the answer.
A chef is attending a big weekend food fair. He is famous for
his egg dishes. He knows that he will need 496 eggs for all of the
dishes he will make. He knows that he will lose 10% of the eggs,
and has ordered enough eggs so that he will end up with the 496 that
he needs. He has ordered 551 eggs delivered to his kitchen.
What formula did he use to come to the conclusion that he will need
551 eggs for the weekend?
I await your reply.

Let x be the number of eggs he ordered. What equation can you use x in which describes this problem?
"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."

Technically the chef should have ordered 552 eggs.
The formula says that he needs 551.111... eggs, and in this situation you round up.
Why did the vector cross the road?
It wanted to be normal.

Yep mathsyperson.
x = 551.11111...
So order 552 eggs
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.

Start with Bobby's equation.
The left side simplifies to 9x/10, and then multiplying both sides by 10/9 gets x on its own.

90% of the required eggs = 496
AND ROUND UP to the next whole number.
