What went well

You worked through formula writing, substitution, and common real-life maths patterns. You also kept going after mistakes, which is exactly how progress happens.

\n\n

Remember these key checks

Start with the subject on the left.
Separate the fixed amount from the repeated amount.
Substitute every value carefully.
Check whether you need to multiply or add.
Give the answer in the right unit.
