Question 1158768
Lbs. of peanuts = p
Lbs. of walnuts = w
<pr>
p + w = 100
1.49p + 2.69w = 2.21(100)
<pr>
p + w = 100
1.49p + 2.69w = 221
<pr>
Multiply first equation by -2.69:
<pr>
-2.69p - 2.69w = -269
1.49p + 2.69w = 221
<pr>
Add equations together:
<pr>
-1.20p = -48
<pr>
p = 40
<pr>
Since we now know p = 40...and p + w = 100...that means w = 60.
<pr>
Lbs. of peanuts = p = <b>40</b>
Lbs. of walnuts = w = <b>60</b>
