Dario Ramirez · Answer 1

104 dollars and 50 cents

Step-by-step explanation:

It's really simple. You just find the total of the hours and multiply it by how much each costs. Simple, right? Let's go through it together.

Since we want to know the total, we do this: 7+9+3

And we know each hour is worth 5 dollars and 50 cents.

So let's make the total "X". Still with me? Let's finish.

So: (7+9+3) * 5.50 = X

(19) * 5.50 = X

104.50 = X
