Copy down formulas based on number in a cell.

I've attached a simple example of what I am trying to do.

I want to copy down formulas in the "Buyer (Example)" tab so that it shows all the items on a list in the MRP tab. (It seems redundant but in the real example it make sense to have a second tab.)
I need to do this using the last number in they "Buy Column" on the MRP tab. The number is 17. I need to copy down the formulas in the "Buyer (Example) tab down 16 rows (17 minus the 1 row I already have.)

The number of items on the "MRP" tab is random every day. It could be 17 items today but 25 items tomorrow.

A demonstration as a starter :

PHP Code: 

Sub Demo1()
    Worksheets("MRP").UsedRange.Columns("A:B").Offset(1).Copy ['Buyer (Example)'!A6]
End Sub

Activating the Macro Recorder and operating manually : you can get your own base of code …

If really formulas are needed :

PHP Code: 

Sub Demo2()
    Range("'Buyer (Example)'!A6:B" & Worksheets("MRP").Cells(Rows.Count, 1).End(xlUp).Row).Formula = "=MRP!A6"
End Sub

Not quite but that's my fault for not being clear and giving a bad example. I've attached an updated file.

The last number in column C of the MRP tab is 5. I want the rows on the "Buyer (Example" tab copied down 5 rows. You could also use something with max in that column because the last number will always be the largest.
