## Linear Programming Word Problem

Rosalyn works no more than 20 hours a week during the school year. She is paid \$10 an hour for tutoring geometry students and \$7 an hour for delivering pizzas for Pizza King. She wants to spend at least 3 hours but no more than 8 hours a week tutoring. Find Rosalyn’s maximum earnings.

I’m not sure how to start this problem:
Given that the heat of fusion of water is -6.02 kJ/mol, that the heat capacity of H2O (l) is 75.2 J/mol*K, and that the heat capacity of H2O (s) is 37.7 J/mol*K, calculate the heat of fusion of water (in kJ) at -14 C.

Any help would be greatly appreciated!!
