The scenario described expressed as an inequality could be written thus :

  • 63m ≥ 300
  • m ≥ 4.76
  • David will need to save $63 for 5 months in other to be able to afford his birthday celebration

  • Least amount required = 300 (≥ 300)
  • Monthly saving = $63
  • Let the number of month required to save = m

The problem could be written thus :

  • (monthly saving × number of months) ≥ amount required

The inequality expression :

  • 63m ≥ 300

Divide both sides by 63 to isolate m

  • m ≥ 300/63
  • m ≥ 4.76

This means that, David will need to save $63 for 5 months in other to be able to afford his birthday cost.
