so... let's rationalize the denominator.. now, the denominator is √(3) - 1, so, we'll use her conjugate,

Answer:
A) .05n + .10d = $1.40
B) n = 2d
We multiply equation A) by -20
A) -n -2d = -28.00 then add it to B)
B) n -2d = 0
-4d = -28.00
dimes = 7
Therefore, nickels = 14
7 dimes + 14 nickels = $1.40
