You can put this solution on YOUR website!

Let:
x=hazelnuts
y=peanuts

Therefore:
x+%2B+y+=+24...........eq.1
7.00x+%2B+4.50y+=+5.54+%2A24
7.00x+%2B+4.50y+=+132.96.........eq.2

By using the substitution method:
y+=+24+-+x.............eq. 1a (from the first equation)
Substituting this value of x into the 2nd equation we can solve for y:
7.00x+%2B+4.50%28+24+-+x%29+=+132.96+
7.00x+%2B+108+-+4.5x=+132.96+
2.5x+%2B+108=132.96+
2.5x+=132.96+-+108
x+=24.96%2F2.5
x+=9.984.........round to the nearest pounds
x+=10
Putting this value of x into the eq.1a we can solve for y:
y+=+24+-+10.............eq. 1a
y+=+14+

Therefore the answer is:
10 pounds of hazelnut
14 pounds of peanuts

Another routine example of this very common kind of two part mix problem


----------------------------------------------------------------
hazelnuts for 7.00 per pound and peanuts for 4.50 per pound how much of each type should be used to make a 24 pound mixture that sells for 5.54 per pound
----------------------------------------------------------------


-----------------------------------------------------------------
nuts1 for H per pound and nuts2 for L per pound. how much of each type should be used to make a M pound mixture that sells for T per pound ?
----------------------------------------------------------------

y pounds of nuts1 at H dollars per pound
M-y pounds nuts2 at L dollars per pound

Hy%2BL%28M-y%29=TM
-
Hy%2BLM-Ly=TM
Hy-Ly=TM-LM
%28H-L%29y=TM-LM
y=%28TM-LM%29%2F%28H-L%29
highlight_green%28y=M%28%28T-L%29%2F%28H-L%29%29%29

Make these substitutions, for YOUR example:
T=5.54 dollars per pound
H=7.00 dollars per pound
L=4.50 dollars per pound
M=24 pounds

Evaluate y, and finish.
