Step-by-step explanation:
Here, the given table is MISSING.
The correct table for reference is attached.
Now, let us assume the hourly rates  of loading/unloading = $ m
Assume the hourly rates  of packing/unpacking = $ n
As given in the table:
3 hours of  loading/unloading + 2 hours of packing/unpacking costs = $480
⇒ 3 m +  2 n = 480
⇒ 2 n =  480 - 3 m  .... (1)
5 hours of  loading/unloading + 2 hours of packing/unpacking costs = $680
⇒ 5 m +  2 n = 680 Â
⇒ 2 n =  680 - 5 m  .... (2)
Now, solving for the values of m and n, we get:
480 - 3 m = Â 680 - 5 m
⇒ 5 m - 3 m = 680 - 480
⇒ 2 m = 200
or, m  = 100
Now,  2 n =  680 - 5 m  =  680 - 5 (100) = 180
⇒ n = 90
Hence, the hourly rates  of loading/unloading = $ m  = $100
The hourly rates  of packing/unpacking = $ n  = $90
