Key learning points

  • Extract the maths from a worded context before calculating.
  • Compare unit prices for best-buy decisions.
  • Show working that a non-specialist could follow — structure marks matter.

Worked example 1 — Best buy

5 for £4£4 or 8 for £6£6. Better value?

Working

8 for £6 (unit 0.75)8\text{ for }£6\ (unit\ 0.75)

Compare unit prices.

Worked example 2 — Service charge

Meal £40£40 + 10%10\% service. Total?

Working

4444

Multiplier 1.11.1.

Worked example 3 — Exchange

£1=$1.25£1=\$1.25. Convert £40£40.

Working

$50\$50

Multiply by the rate.
