PLEASE HELP!!! Jeanie is 21 years old. She opens an account that pays 3.9% interest compounded monthly. She
Harlamova29_29 [7]

Answer:

$11,170

Step-by-step explanation:

First you convert the percentage to decimal form out of 100 (which you divide)

3.9%/100 =  0.039

A = P(1 + rt)

A = 10000(1 + 0.039 * 3)     ( * = multiplication)

I = $11,170 - 10,000 = $1,170

Which you should get $1,170.00 or $1,170 (which is pretty much the same thing)

Hope this helps!

Strike441 [17]
\left\{\begin{array}{ccc}5x-y=5&|subtract\ 5x\ from\ both\ sides\\5x-3y=15\end{array}\right\\\left\{\begin{array}{ccc}-y=-5x+5&|change\ the\ signs-multiply\ both\ sides\ by\ (-1)\\5x-3y=15\end{array}\right\\\left\{\begin{array}{ccc}y=5x-5&(1^o)\\5x-3y=15&(2^o)\end{array}\right\\\\subtitute\ (1^o)\ to\ (2^o)\\\\5x-3(5x-5)=15\\5x-3(5x)-3(-5)=15\\5x-15x+15=15\\-10x+15=15\ \ \ \ |subtract\ 15\ from\ both\ sides\\-10x=0\ \ \ \ \ |divide\ both\ sides\ by\ (-10)\\\boxed{x=0}
