Question

Could someone please help?

Answer 1

So if it is 1/3 of 90 it would be 30 tiles. So you have to do 30 times the cost 2.69 which makes the cost the job 80.70

Answer 2

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).
