Q2 should be obvious.

3. Problem is misstated; the formula is FVOA = C*(not plus) (1+i)^(nt)-1)/i ,
n=12, t=35 and i is r/n, where r is the rate and n the number of compoundings per year.
1+(.05/12)=1.0041666667 don't round until the end
raise that to the 420 power and subtract 1.  That will be 4.73337 but keep all numbers.
divide by (.05/12) and multiply by C or 1000.
that will give $1,136,092.43
