Answer:

2 packs.

Step-by-step explanation:

Each sticker pack is 21 stickers and you would want to get 50 in total.

Since he already has 8 stickers, the initial value is 8.

So, 50-8 is 42. That means Anthony would need 42 more stickers to reach 50.

At this point, you can do division \frac{42}{21} and that would give you 2.

You can check your work by working backwards and seeing that 2(21)=42.

42+8=50.

First, let's declare some variables.

x = # of sticker packs

y = total # of stickers

Now, let's create an equation to model the problem.

y = 21x + 8

Let's plug in 50 for y and solve for x.

50 = 21x + 8

Subtract 8 from both sides.

42 = 21x

Divide both sides by 21

2 = x

Anthony will have to buy 2 sticker packs to have a total of 50 stickers.
