Understanding the Context

At its core, a 15% price increase means the original value is multiplied by 1.15. Why 1.15? Because 15% expressed as a decimal is 0.15, so adding it to 1 gives the proportional multiplier:

Original Price × (1 + Percentage Increase)
= Original Price × 1.15

If you know the new price after the increase is $230, you can reverse-engineer the original price using this formula:

Original Price = Final Price ÷ 1.15

Key Insights

Example: $200 Becomes $230 After a 15% Increase

Plugging into the formula:

$230 ÷ 1.15 = $200

This shows that $200, when increased by 15%, results in $230:

• 15% of $200 = $30
  
• $200 + $30 = $230

This straightforward calculation applies whether the original price was $200 or any base value increasing by 15%.
