Answer:
- 25 pounds cashews
- 15 pounds peanuts
Step-by-step explanation:
Let c represent the number of pounds of cashews in the mix. Then 40-c is the number of pounds of peanuts. The total cost of the mix is ...
10c +2(40 -c) = 7(40)
8c +80 = 280 . . . . simplify
c +10 = 35 . . . . . . . divide by 8
c = 25 . . . . . . . . . . subtract 10
40-c = 40-25 = 15 . . . . pounds of peanuts
25 pounds of cashews and 15 pounds of peanuts should be used in the mix.
22/30 = 11/15
7/9 = 14/18
18/54 = 1/3
10/17 = 20/34
A proportion can be set up by using the general formula:
a/b = c/d
ad = bc
