Answer:
Step-by-step explanation:
Given the exponential decay function 
When 
then
so the initial amount is 
The exponential decay function 
has the decay factor 
In your case, the eexponential decay factor is 
.09:
"of" means that you have to multiply.
1/10 is equal to .1
If you multiply 0.1 by 0.9 you will get .09
Answer:
Answer is 600

Answer:
Five= 9 One= 6 Twenty= 15
Step-by-step explanation:
A cashier has a total of 30 bills, made up of ones, fives, and twenties.
o+f+t=30,
The number of twenties is 9 more than the number of ones.
t=9+o,
The total value of the money is $351.
o+5f+20t=351
so we have
o+f+t=30, t=9+o,
o+5f+20t=351
f = 9, o = 6, t = 15
