alleryThe first step in solving a real-world problem with maths is to:
ABuild a model
BCheck the answer
CRound the numbers
DRecall a formula
Answer & Solution
Correct answer: A. Build a model
1. Real problems must first be translated into mathematics.
2. So the first step is to construct a mathematical model.
3. Checking comes after the solution is back in context.
