Ответ:
The way B is worded is a bit weird to me, but if I understand it correctly, Part B is simple now that we have the expression because we can plug in the value for the variable c. 120/1.5 is 80. If Fiona eats 1.5 cups of grain per day (much more reasonable than my exanple of 40 above, lol), then she would have grain for 80 days.
