Answer:
C. $5.55
Step-by-step explanation:
Total cost of installing 60 square feet of flooring 
= $253.00 + $80
= $333
Total number of square feet for flooring = 60
Now cost per square foot of the flooring 
= total cost/total number of square feet 
That’s
$333/60 = $5.55
Each square foot cost $5.55

Answer:
66.7 in^3
Step-by-step explanation:
The volume of a triangular pyramid is given by
V = 1/3 B h
 where B is the area of the base and h is the height
Calculate the area of the base.  The base is a triangle
B = 1/2 bh  where b is 8 and h is 5
   = 1/2 (8) * 5
   =20
V = 1/3 (20) 10
  66.6666666
To the nearest tenth
