Answer:
Two boxes will cost 
The cost of one tile is approximately 
Step-by-step explanation:
Note that 1 ft = 12 in, then
The area of the floor is
Now
then
144 sq. in - 1 tile,
9540 sq. in - x tiles.
Mathematically,
tiles is needed to cover the floor (67 full tiles).
Each box of tiles contains 45 tiles, so Cristina has to buy 2 boxes. These two boxes will cost The cost of one tile is approximately

Answer:
The coordinates of endpoint B are (15, 5).
Step-by-step explanation:
This problem gives you the midpoint coordinates of line segment AB, and the coordinates of endpoint A. Given this, you can find the "distance" between the two points and thus the "distance" between the midpoint and point B.
Start by subtracting the the coordinates of point A from the coordinates of the midpoint.
X: 9-3=6
Y: 7-9=-2
X travels along the horizontal axis, while Y travels along the vertical axis. This means that a positive X goes right, a negative X goes left, a positive Y goes up, and a negative Y goes down.
Because you have a positive 6 for X, the line traveled 6 units right from point A to the midpoint. And because you have a negative 2 for Y, the line traveled 2 units down from point A to the midpoint.
Now, going from the midpoint to your unknown point B is simply shifting the discovered number of units right and down, or adding and subtracting from your midpoint accordingly.
M(9, 7)
B(9+6, 7-2)
B(15, 5)
