(just need help explaining what formula I have to do to get my answer.) Glenn invested $22,000 at 7% interest compounded annually. How much interest will Glenn earn in 3 years?
\[\huge A = P(1+\frac{ r }{ n })^{nt}\] compound interest formula should suffice. P = Principle amount r = Annual rate of interest t = Number of years A = Amount of money accumulated after n years n = Number of times the interest is compounded per year
$$\huge A = P \left( 1+\frac{ r }{ n } \right)^{nt}$$
sorry confused am I supposed to use the 1 in every formula so that I can get my answer?
Yes!
how do I find n?
`Glenn invested $22,000 at 7% interest compounded annually` what does annually mean
every year so 22000 x 3 would be n?
No the interest is compounded annually so n = 1
make sure ur writing ur interest in decimal form
im doing the formula but I must be doing something wrong because none of the answers I get are right
Let me ask you, which variable are we solving for
um sorry I don't really know variables but I'm thinking 3 is the variable ??
Are we solving for A, p, n, r, t?
a? idk we are solving what 22,000 at 7% would be in 3 years
\[A=22000(1+\frac{ 0.07 }{ 1 })^3\]
Yes @mavckenzie, ayesh has plugged in all the values for you please see if you understand it.
