Find the accumulated amount after 4 years if $5,000 is invested at 8% per year compounded continuously. a) $6,262.79 b) $6,885.64 c) $16,000 d) $5,160 5. Find the total value of the investment of $55 at 7% compounded daily for 2 years. a)$63.26 b)$62.97 c) $62.70 d)$55.02

Explanation / Answer

f(x) = 2x - 1 ; f(4)=7; 2)2x-y=7; y=8-3x; 2x+3x=15; x=3; y=-1; point(3,-1) 3)straight line; y=mx+c; 4) A=P(1+r/100)^n; =5000(1+0.08)^4; = $6,885.64; 5) A=55(1+0.07)^2; = $62.9695 b is answer; in quest number 5 ompounded yearly inplace of daily for 2 years.
