Get Last Record of same ColumnID

i am currently stuck on the following Task:

i have a table that Looks similiar to this one

| TableID | EntityID | InvoiceAmount|      Date      |
|     1      |  46       | 300000         |14-01-2014|
|     2     |  232      | 2456,63          |17-01-2014|
|     3      |  46       | 400000          |22-01-2014|
|     4      | 232      | 333000         |31-01-2014|
|     5      |  12       | 124                |11-01-2014|
|     6      |  46       | 300000         |31-01-2014|

What i Need is the last Invoice amount by EntityID according to the Date Column, so in the Case of EntityID 46 this would be the 31-01-2014, and the Value of the Entity would be: 300 000.

Question: Is there a way to do this in SQL or what other Option do i have ?

thanks a lot in Advance!
