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?
