Answer:
It is growth and the percentage rate of increase is 7.5%
Step-by-step explanation:
The exponential equation is as follows;
y = 550(1.075)^x
Now, I can identify that the exponential equation is that of growth.
This is because what is in the bracket i.e can be represented as 1+ 0.075
The 0.075 represents the margin of increase as we move on from one value to another
The percentage rate can be gotten by expressing 0.075 as a percentage
That would be expressing is as a fraction
This is just 7.5/100 which means what we have is 7.5%
Answer: x = 1
Step-by-step explanation:
Step 1: Cross-multiply.
x/8 = 8/64
x*(64)=(8)*(8)
64x=64
Step 2: Divide both sides by 64.
64x/64 = 64/64

Therefor, the answer is x = 1

Answer:
The cost to fill the new family size box will be 
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z-----> the scale factor
we have

so

To find the new cost multiply the original cost by the scale factor elevated to the cube

The new volume would be
