The small package will cost Tony 2.50 to send.
The large packages will cost Tony 3 * 4.40 = <<3*4.40=13.20>>13.20 to send.
Thus, it will cost Tony 2.50 + 13.20 = <<2.50+13.20=15.70>>15.70. Answer: \boxed{15.70}.
The large packages will cost Tony 3 * 4.40 = <<3*4.40=13.20>>13.20 to send.
Thus, it will cost Tony 2.50 + 13.20 = <<2.50+13.20=15.70>>15.70. Answer: \boxed{15.70}.
Let's start with the small packages:
Each small package costs Tony $2.50 to send.
So, the cost of sending 1 small package is $2.50.
Now let's move on to the large packages:
Each large package costs Tony $4.40 to send.
Since he wants to send 3 large packages, the total cost will be:
3 * $4.40 = $13.20.
Finally, let's calculate the total cost:
The cost of sending 1 small package is $2.50, and the cost of sending 3 large packages is $13.20.
To find the total cost, we add these two amounts together:
$2.50 + $13.20 = $15.70.
Therefore, it will cost Tony $15.70 to send 1 small package and 3 large packages.
For Tony to send 1 small package, it will cost him $2.50.
For Tony to send 3 large packages, it will cost him 3 * $4.40 = $13.20.
To find the total cost, we add the cost of the small package and the cost of the large packages: $2.50 + $13.20 = $15.70.
Therefore, it will cost Tony $15.70 to send 1 small package and 3 large packages.
