Yes the answer would be B
6x5+24x3+3x3+12x ------> Simplify by adding like terms
6x5 + 27x3 + 12x
125 is equivalent to
<em>1.25</em>
<em>1 1/4 </em>
<em></em>
Pick either one... 1.25 is more likely to be correct

What you can use for this case is a function of the potential type.
We have then
y = a (b) ^ x
Where we have:
Walker starts the fund by depositing $ 5
a = 5
Each week the balance of the fund is twice the balance of the previous week:
b = 2
The function is:
y = 5 (2) ^ x
The number of weeks to reach $ 1280 is 8 weeks.
Check:
y = 5 (2) ^ 8
y = 1280
Answer:
An equation can be used to find the number of weeks, x, after which the balance of the fund will reach $ 1,280 is:
y = 5 (2) ^ x
The number of weeks that it takes to reach the class goal is
8 weeks
Could you do 31 add 31 which would also be 31 multiplyed by 2
hope this helps
