2N+4M=194 NOW MULTIPLY THIS EQUATION BY -2.5 THEN ADD THEM.
7N+10M=650
-5N-10M=-485
------------------------------------
2N=650-485
2N=165
N=165/2
N=$82.50 IS THE NIGHT RATE.
2*82.5+4M=194
165+4M=194
4M=194-165
4M=29
M=29/4
M=$7.25 IS THE MEAL RATE.
PROOF.
7*82.50+10*7.25=650
577.5+72.5=650
650=850
