Chris mixed 3 pounds of raisins with 4 pounds of nuts. If a pound of nuts costs 3 times as much as a pound of raisins, then the total cost of the raisins was what fraction of the total cost of the mixture?
A. 1/7
B. 1/5
C. 1/4
D. 1/3
E. 3/7
The OA is B.
1 lbs of raisin = $1
3 lbs of raisin = $3
1 lbs of nuts = $3
4 lbs of nuts = $12
Total value of mixture = 12+3 = 15
Fraction of the value of raisin = 3/15 = 1/5
Please, can anyone explain another way to solve this PS question? Thanks!
