Hi guys, I'm having a problem with one math question. Please
help me out. Here's the questions "Mrs Lim buys 30 kg of cheese
at a certain price. She finds that if she had bought some
cheaper cheese costing 95 cents less per kg, she could have had
32.5 kg for the same amount of money. What is the price per kg
of the cheese which is more expensive?" The answer to this
however question is $12.35. But I don't know how this question
is solved, I don't know how to form the equation. What is the
proper equation?
