How much more money do 10 t-shirts cost that 6 t-shirts? explian how you found your answer.

Well if the t-shirts are the same amount of money per shirt, then you simply work it out like this.
EXAMPLE
1 t-shirt = $10
So if you need to buy 10 you just multiply 10 by 10.
10x10= $100
Also if you need to find the difference between buying 6 or 10 you subtract the two numbers which would be 4 then divide 100 by 4.
