Number 27:
~So if Julia wants 1/3 of her 90 tiles replaced then she will need to replace 30 tiles.
1/3 of 90 = 30
Next, you have to multiply 30 by the price per tile.
30 x $2.69 = 80.70
_____________________________________________________________
~Julia will have to pay $80.70 to replace 1/3 of her tiles (30 tiles).
Hope this helps!!! :D
