Answer:
30%
Explanation:
4 pounds of almonds is $22 --> 1 pound of almonds is $5.50
Cashew price per pound = 160/100 * $5.50. = $8.80
22 + 8.80x = 6.50(4+x)
22 + 8.80x = 26 + 6.50x
2.30x = 4
x = 1.739130435 approx 1.74 lbs of cashews
percent of the mixture, by weight, for cashews =
1.739130435 / (4 + 1.739130435) = 0.303030303 approx 30%
