0.54 is the simplified answer I got from that.

0.10d + 0.05n = 3.75 -- multiply this by 100 to get rid of decimals
10d + 5n = 375
d = 7n

10(7n) + 5n = 375
70n + 5n = 375
75n = 375
n = 5

d = 7n
d = 7(5)
d = 35

there is 35 dimes (which equals 3.50) and 5 nickels (which equals 0.25) for a total of 3.75
