lets call the number of soft serve s
and the number of hard pack h
s+h=77........eq 1
2s+.75h=119...eq 2
:
solver for s in eq 1 and substitute its value into eq 2.
:
s=77-h
:
2(77-h)+.75h=119
154-2h+.75h=119
1.25h=35
highlight%28h=28%29 number of hard pack cones
highlight%28s=77-28=49%29 number of soft serve cones
