answer:
$646.50
work:
5.5% of 300 is 16.50
16.50×21 (how long it is in there)=346.50
346.50(how much you made in 21 years)+300(the amount already in)= $646.50
a) Using the given recurrence,
b) Proceeding as above, you'll find that successive values of 
, starting at n = 7, gravitate towards a solution of about -0.254102.
Answer:
(7x^2 -1)(x - 2).
Step-by-step explanation:
7x^3 - 14x^2 - x + 2
We can factor this by grouping - that is factoring the first 2 terms and the last 2:
= 7x^2(x - 2) - 1(x - 2) <-- the x - 2 is common to both parts so we have:
(7x^2 -1)(x - 2).
X-amount of cleaning soulution
1Gal=x+3x
1Gal=4x
x=1/4 Gal
The amount of solution needed will be 0.25 Gal.
Hope it helped!
