Answer:
   A(x) = 20000(0.88)^x
Step-by-step explanation:
The general form of these exponential equations is ...
   A(x) = a·b^x
where 'a' is the initial value, and b is the annual growth factor. x is the elapsed time in years.
The growth factor is ...
   growth factor = 1 + growth rate
Here, the growth rate per year is -12%, so the growth factor is ...
   b = 1 -12% = 88% = 0.88
Of course, the initial value is a=20,000, so the equation is ...
   A(x) = 20000(0.88)^x

Answer:
Step-by-step explanation:
Equation is t÷5=8
first you multiply 5 on each to cancel it out
t÷5*5=8*5
solve to get 
t=40
 
        
             
        
        
        
Answer:
Approximately 4.67 feet of fabric is required for one pillow case.
Step-by-step explanation:
We are given the following in the question:
Number of pillow cases to be made by Jenny = 3
Amount of fabric Jenny has = 14 feet
Each pillow case use same amount of fabric.
Amount of fabric used to make 1 pillow case = 

Thus, approximately 4.67 feet of fabric is required for one pillow case.
