Ineed to collect 30 stickers. each bag of crisps contains 3 stickers. how many bags will i need to buy?

Hey there :)

Let p represent the number of bags to be bought

We need to collect 30 stickers and each bag has 3 stickers

                    3p                                =                        30
                      ↑                                                           ↑
Number of stickers in a bad       Number of stickers to be collected

= 
p = 10

We need to buy 10 bags of crisps to have 30 stickers

You need to collect 30 stickers and each bag of crips contains 3 stickers.

So; you just have to devide the total of stickers you need by the stickers contained in one bag.

So, let's call p the number of stickers.





In short, you'll need to buy 10 bags.

Hope this helps !
