Assume abc company deposits $90,000 with first national bank in an account earning interest at 6% per annum, compounded semi-annually. how much will abc have in the account after five years if interest is reinvested?

Step-by-step explanation:

I'm goig to assume that the formula we need here is the following:

where A(t) is the amount in the account after the compounding is done, n is the number of times per year the compounding occurs, r is the rate in decimal form, and t is the time in years.  Filling in accordingly,

and simplifying a bit,

and simplifying a bit more,

A(t) = 90000(1.343916379) so

the amount in the account after 5 years is

A(t) = 120,952.47

a² + b²= c²

24² + 7² = c²

c= 25
