A) f(x)=0.2x
B)f(12)=0.2(12)=2.4 dollars
Given is :
The area of the deck will be = 64 square feet.
As, it is not mentioned if the deck is a rectangle or a square, so we can assume it can be both,
For square it will be.
Area = side * side
Let the side be = x
![x*x=64](https://tex.z-dn.net/?f=x%2Ax%3D64)
![x^{2}=64](https://tex.z-dn.net/?f=x%5E%7B2%7D%3D64)
![x=\sqrt{64}=8](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B64%7D%3D8)
So, side of the deck will be 8 feet.
For rectangle it will be.
As the dimensions are not given, we can find them by finding the multiples of 64.
The multiples are : 1.2,4,8,16,32
So to make 64, the possible combination can be either 2*32 or 4*16
Hence. if the deck is rectangular, so one set of length can be 16 feet and 32 feet. And set of width can be 4 feet and 2 feet.
You divide the top by the bottom. 8/18=.44
Answer:
$3800
Step-by-step explanation:
30 x 2 = 60
60 + 3 = one container
60 containers = 63 x 60
3780 + 20
3800
