Choose a number for the beige tiles.

Add to the number of beige tiles to give you the number of red tiles.

Multiply the number of beige tiles by to get the number of navy-blue tiles.

Add the beige, red, and navy-blue tiles together to get the total number of tiles Susan bought. Did your total come out to ? If not, try another number for the beige tiles.
