Let n ounces of a 15% acid solution be mixed with m ounces of a 55% salt solution.
Which of the following are possible salt concentrations of the mixture? (Select all that apply.) 

10%     - impossible

40%     - possible, depending on  "n"  and  "m"

45%     - possible, depending on  "n"  and  "m"

50%     - possible, depending on  "n"  and  "m"

85%     - impossible

The recipe is: Only values in between 15% and 55% are achievable.
