Cost = #$135#

Explanation:

Purely from an area comparison, the minimum cost will be the minimum allowed size with the larger tiles. So, you just need to fit the dimensions of the large tile to a mosaic dimension within the two bounds. Because the 12"x6" tile will fit exactly within the minimum 60"x36" mosaic size, that is the way go.
It will require 6 rows in 5 columns, for a total of 30 tiles.
Cost = #$135#

The similar area with 4"x4" tiles would require 135 tiles for a cost of #$472.50#
