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?
Let's think step by step below.
300
Accommodation is 15% * $1000 = $150.

Food is     30% * $1000 = $300.

Entertainment is  25% * $1000 = $250.

Coursework materials are thus $1000 - ($150 + $300 + $250) = $300.

.

Thus, the answer is 300
