Bentley Conrad · Answer 1

For this case we have.

"Dalia has 152 tiles available to tile the room"

"19 tiles break while Dalia is laying the floor,"

So:

152-19 = 133 tiles available.

Then,

"If each row requires 9 1/2 tiles"

We have then that the number of rows is:

N = 133 / (9 1/2)

N = 14 rows

Answer:

she can install 14 full rows of unbroken tile before running out of tiles
