Answer:
- 5 lb of strawberry leaves
- 8 lb of orange slices
Explanation:
Let "o" and "s" represent the number of pounds of orange slices and strawberry leaves in the mix, respectively. We want ...
o + s = 13 . . . . . . . . . . . . . . . total weight
1.29o +1.79s = 19.27 . . . . . .total cost
Solving the first equation for o, we can substitute that result into the second equation to get ...
o = 13 -s
1.29(13 -s) +1.79s = 19.27
0.50s +16.77 = 19.27 . . . . eliminate parentheses
0.50s = 2.50 . . . . . . . . . . . subtract 16.77
s = 5 . . . . . . . . . . . . . . . . . . multiply by 2
o = 13 -5 = 8
5 pounds of strawberry leaves should be mixed with 8 pounds of orange slices to get the desired mixture.
