Serggg [28]

First, we calculate for the effective interest given the annual interest and the condition that it is compounded monthly.

<span>                                                Ieff = (1 + 0.0925/12)^12 – 1 = 0.09652</span>

The equation that would best represent the value of Grace’s money after x years is equal to,

<span>                                               An = ($1000)(1.09652)^x</span>

Solve the following equation for r2: Q = 2sL(T2-T1)/ln(r2/r1)
Sergeu [11.5K]
Q=2*s*L(T2-T1)/ (R2/R1)
1500000=2*30*10(275-22)/(R2/6)
1500000=600(253)/(R2/6)
1500000R2=600*253*6
1500000R2=910800
R2=910800/1500000
R2=0.6072.
