Question 858211
d count of dimes
n count of nickels
-
d=n+6 and 0.05n+0.1d=3.15 which is n+2d=63.
The system most simplified is:
_____________________
d-n=6
_____________________
2d+n=63
_____________________


Just add the two equations to use Elimination Method.
This immediately gives 3d=66, meaning {{{highlight(d=22)}}}.
