  1. Compute 100(1+0.05/12)^24
100*(1+0.05/12)^2
## [1] 100.8351
  1. Remainder of 3333 divided by 222?
3333%%222
## [1] 3
  1. Investigate behaviour of (1+1/n)^n, for large values in n
ha<-c(1,10,100,1000,10000,100000,1000000,10000000)
 
 for(n in ha[1:8]){
 newval<-(1+1/n)^n  
 cat("n = ", n,"\t(1+1/n)^n = ",newval, "\n")
 
 }
## n =  1   (1+1/n)^n =  2 
## n =  10  (1+1/n)^n =  2.593742 
## n =  100     (1+1/n)^n =  2.704814 
## n =  1000    (1+1/n)^n =  2.716924 
## n =  10000   (1+1/n)^n =  2.718146 
## n =  1e+05   (1+1/n)^n =  2.718268 
## n =  1e+06   (1+1/n)^n =  2.71828 
## n =  1e+07   (1+1/n)^n =  2.718282
  1. The Economic Order Quantity (EOQ) gives the optimal order quantity as Q=sqrt(2DK/h) where D is the annual demand, K is the fixed cost per order, and h is the annual holding cost per item. Create and set the variables D=1000D=1000, K=5K=5, and h=0.25h=0.25 and compute the associated value of Q
 D<-1000
 K<-5
 h=.25
 Q<-sqrt(2*D*K/h)
 Q
## [1] 200
  1. For an initial principal amount P and a nominal annual interest rate r that is compounded n times per year over a span of t years, the final value of a certificate of deposit is F=P(1+r/n)^nt. Create and set variables P=100,r=0.08,n=12 and t=3 and compute the associated value of F.
 P<-100;r<-0.08;n<-12;t<-3;
 F<-P*(1+r/n)^(n*t)
 F
