S3 Finance and Net Income

Work with income, deductions, budgets and comparisons between financial choices.

What to practise

Start by identifying the information in the question, choose a suitable method, and check whether the result is reasonable. Where a picture, graph or diagram helps, the protected practice flow uses one to make the relationship easier to see.

Worked example

Practice questions build from a clear example to more demanding applications. Read the units, labels and values carefully, then explain the method in your own words.

Support after a mistake

Helpful hints appear after incorrect answers. A second stage gives a different worked example with ordered steps before you retry. This is practice support, not a formal assessment.
