Hello I'm a university student who hasn't done any maths in the last 3 years or so. Basically im a law/commerce student and one of my core subjects for commerce is economic. I done economics in high school and was amongst the highest. However high school economic has very little maths and is more just theory. So one of the things I need to know is how to use algebra for demand and supply. I attached the questions I cant answer hopefully someone can teach me. Tutorial 2_a.pdf 6,8,9,10 are questions I can answer. Its no problem if noone can help but i would appreciate if someone tries. Thanks Lisa.
