A tea company intends to pack tea into 200g packets and sell them at such a price to make a 30% profit. The machines are set incorrectly and put in too much tea. Only 25% profit is made. How much extra tea is put in each packet?

If you don't want to use algebra, one way to start would be to suppose that tea costs $1 per gram. How much would they have to charge for one packet to make a 30% profit?

Then, if at that price they make a 25% profit, what must the actual cost of the tea have been?
