Lizzy: James is a first-year student at a University in Chicago. He has a budget of $1000 per semester. He spends 30% of his money on food, 15% on accommodation, 25% on entertainment, and the rest on coursework materials. How much money does he spend on coursework materials?.
Me: Hmmm, let me think. I think this is the detailed solution:
Accommodation is 15% * $1000 = $150. Food is 30% * $1000 = $300. Entertainment is 25% * $1000 = $250. Coursework materials are thus $1000 - ($150 + $300 + $250) = $300. Final answer: 300.
