Question

Rafael has a sheet with 100 stickers. He gives n stickers to each of his 6 cousins. Write an expression that represents the number of stickers Rafael has left. Then evaluate the expression for n=7

Answer 1

100-6n, 58 stickers

Explanation:

100-6n is our expression because Raf starts with 100 stickers, but gives away (so subtraction) n stickers to each of his 6 cousins, hence 6n.

Now we can solve the expression given n=7:

100-6*7=

100-42=

58 stickers left

I hope this helps! :)
