  • A week 18.7p × 7 = £1.31 · a month × 30 = £5.62 · a year × 365 = £68.39
  • Amount per serving: stated on the label.

Vitamin C

  • Servings: 120 ÷ 1 per serving = 120
  • In the pack: 120 × 24 mg = 2.88 g
  • £14.99 ÷ 2.88 g × 1 g = £5.20 per 1 g
  • A week £5.20 × 7 = £36.43 · a month × 30 = £156.15 · a year × 365 = £1899.77
