Answer:
The multiplicative rate of change is 
Step-by-step explanation:
You are given the function

First, use the following property of exponents

So, your function is

If the exponential function is written in the form

then b is the multiplicative rate of change for this exponential function.
In your case, the multiplicative rate of change is 
To find the answer you would multiply 1,300 by .06, which gives you a commission of $78.

Answer:
The value of x is
hours.
Step-by-step explanation:
Machine A = 5 hours
Machine B = x hours
Machine A and B = 2 hours
Using the formula: 
where:
T is the time spend by both machine
A is the time spend by machine A
B is the time spend by machine B

Let multiply the entire problem by the common denominator (5B)

2x + 10 = 5x
Collect the like terms
10 = 5x - 2x
10 = 3x
3x = 10
Divide both side by the coefficient of x (3)

hours.
Therefore, Machine B will fill the same lot in
hours.
