Step-by-step explanation:
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 = 10We need to buy 10 bags of crisps to have 30 stickers
p(10) is the profit, in dollars, from selling 10 books. Replace every copy of x with 10 and simplify
p(x) = 8x-10
p(10) = 8*10-10 .... every x is replaced with 10
p(10) = 80-10
p(10) = 70
So the profit is $70
