A mail gardening equipment business shipped 119 packages in one day. Customers are charged 4.50 for each standard delivery package and $9.00 for each express delivery package. Total shipping charges for the day were $720. How many of each package were shipped. There were _ standard delivery packages and_ express delivery packages shipped

Let's assume the number of standard delivery packages shipped is x and the number of express delivery packages shipped is y .

We know two things:
1. The total number of packages shipped is 119, therefore x + y = 119 .
2. The total shipping charges for the day were 720, therefore 4.50x + 9y = 720$.

Solving the system of equations:
From equation (1):
x = 119 - y

Substitute x in equation (2):
4.50(119 - y) + 9y = 720

535.50 - 4.50y + 9y = 720

4.50y = 184.50

y = 41

Substitute y back into equation (1):
x = 119 - 41

x = 78

Therefore, there were 78 standard delivery packages and 41 express delivery packages shipped.

\boxed{78 \text{ standard delivery packages and } 41 \text{ express delivery packages shipped}}
