jim_thompson5910 · Answer

c cherries cost d dollars

we have this ratio

c cherries : d dollars

divide both expressions by 'c' to get

c/c cherries: d/c dollars
which simplifies to
1 cherry: d/c dollars

this means 1 cherry costs d/c dollars

does that make sense so far?

amtran_bus · Answer

Oh! I have not thought of it that way. Sure does!

jim_thompson5910 · Answer

from there I'm sure you can see how 50 costs 50*(d/c) = 50d/c

amtran_bus · Answer

Sure enough! Thanks a million!
