Hope this will help
Ответ:
Let y be the number of oranges
x+y≤20
0.24x+0.8y≤12
x≤20-y
0.24(20-y)+0.8y≤12
4.8-0.24y+0.8y≤12
0.56y≤7.2
y=12.9 (you can choose 12 here, since you can't have a fraction of an orange sold)
x= 7.14 (again, rounding this off to 7)
Therefore, Darcy got 12 oranges and 7 apples.
Hope I helped :)
