Victoria had $200 in her account at the end of one year. at the first of each subsequent year she deposits $15 into the account
and earns 2% interest on the new balance, compounded annually. which recursive formula represents the total amount of
money in victoria's account at the end of the nth year?
a, - 1.02( a -1 +15), aq - 215
an - 15+1.02a -1, 2, - 215
2,- 1.02(an-1 +15); a, - 200
an = 15+1.02am-11 an - 200

The amount of money in Victoria's account at the end of n-th year will be,

$

Step-by-step explanation:

The amount of money in Victoria's account at the end of n-th year will be,

$

= $

= $

= $

Since, the interest is compounded over that $ 200 (which was there in the account at the end of 1st year) for (n-1) years and for (n-1) years, (n-2) years, (n -3) years, ...... 1 year respectively over those $ 15 which are deposited in the account at the end of 1 , 2, 3, ...... (n-1) years.

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
