Hi there,
Many thanks in advance for the help.
Here is the equation I am struggling to solve:
110 = 1/(1+r) x 32.1/r
How I solve for "r", or perhaps find an LCD with these denominators?
Thanks so much,
Naldo
assuming the "x" meant multiplication ...110 = 1/(1+r) x 32.1/r
$\displaystyle 110 = \frac{32.1}{r(r+1)}$
$\displaystyle r(r+1) = \frac{32.1}{110}$
$\displaystyle r^2 + r - \frac{32.1}{110} = 0$
recommend using the quadratic formula ...
