Read the story.

Pedro has 150 cake pops. He plans to sell them in packs of 2 and charge $6 for each pack.
Which expression tells you the amount of money Pedro could make in all?

To find the amount of money Pedro could make in all, we can use the expression:

$6/pack * (150 cake pops / 2 cake pops per pack)

This simplifies to:

$6 * 75 = $450

Therefore, Pedro could make $450 in all by selling all 150 cake pops in packs of 2 for $6 each.
