Sure, I'd be happy to help you solve this problem.

First, let's calculate how much each girl spent. Joy spent 30 * $4 = $120. Colleen spent 50 * $4 = $200.

To find the difference in how much they spent, we can subtract Joy's cost from Colleen's cost, which is $200 - $120 = $80.

So, Colleen spent $80 more than Joy did.

I hope this helps!

Sure, let's break this down:

1. First, we need to calculate how much Joy spent on her pencils. She has 30 pencils and each pencil costs $4. So, Joy spent 30 (pencils) * $4 (per pencil) = $120.

2. Next, we calculate how much Colleen spent on her pencils. She has 50 pencils and each pencil also costs $4. So, Colleen spent 50 (pencils) * $4 (per pencil) = $200.

3. Now, to find out how much more Colleen spent than Joy, we subtract the amount Joy spent from the amount Colleen spent. So, Colleen spent $200 - $120 = $80 more than Joy.

So, Colleen paid $80 more than Joy for her pencils.
