Answer:
n = d+30 since he has 30 more nickels than dimes, to make them equal you have to add 30 to the dimes.
:
n+d = 150 substitute for n:
d+30+d = 150
2d = 120
d = 60 he has 60 dimes and 150-60 = 90 nickels
Everything should add up to 100%. So do
20 + 40 + 10 + 5 = 75
Now subtract 75 from 100
100 -75 = 25
25%
