you have volunteered to make a nut mix for a dinner party.
the host tells you need to make enough mix for 40 people
(each person will eat 1/8 pounds of mix each)
shelled walnuts cost $7.49 per pound and
milk chocolate covered cashews cost $6.99 per pound.
you spend a total of $35.70
how many pounds of each nut did you purchase.
---------------------------------------------------------
Let walnuts=w; c=cashews
-------------------------
Weight equation: w + c = 40*(1/8) = 5
Value equation: 7.49w + 6.99c = 35.70
-------------------------
I guess you can take it from there.
Cheers,
Stan H.

40*1/8=5 lbs. of mixed nuts are prepared.
7.49x+6.99(5-x)=35.70
7.49x+34.95-6.99x=35.70
.5x=.75
x=.75/.5
x=1.5 lbs. of shelled walnuts are used.
5-1.5=3.5lbs. of milk chocolate are used.
proof:
7.49*1.5+6.99*3.5=35.70
11.235+24.465=35.70
35.70=35.70
