Question 1015996
.
I do not think you proof read your problem,
but this will show you how to find the answer
with the correct numbers.
.
P=cost of peanuts; C=cost of cashews=3P; A=cost of almonds=218218P
Total weight of mix= 7 pounds + 2 pounds + 5 pounds = 14 pounds
.
(7lbs)C+(2lbs)A+(5lbs)P=(14lbs)$76.88
(7lbs)(3P)+(2lbs)(218218P)+(5lbs)(P)=1076.32
21P+436436P+5P=1076.32
436462P=1076.32
P=$0.0025 per pound
Peanuts cost 0.25 cents per pond
.
C=3P=3($0.0025/pound)=$0.0075/pound
.
ANSWER: Cashews cost $0.0075 per pound (3/4 cent per pound)
.
CHECK:
.
A=218218P=218218($0.0025)=$538.13 per pound
Almonds cost $5338.13 per pound
.
(7lbs)C+(2lbs)A+(5lbs)P=(14lbs)$76.88
(7lbs)($0.0075/lb)+(2lbs)($538.13/lb)+(5lbs)($0.0025/lb)=(14lbs)$76.88
$0.0525+$1076.26+$0.0125=$1076.32
$1076.325=$1076.32 (.005 cent discrepancy from rounding)
