How to calculate the total cost for multiple pairs of kids’ sunglasses?

The total cost can be calculated using the following formula:

Total Cost (TC) is calculated as:

§§ TC = (P × N) × (1 - D/100) × (1 + T/100) §§

where:

  • § TC § — total cost
  • § P § — price per pair of sunglasses
  • § N § — number of pairs purchased
  • § D § — discount percentage
  • § T § — tax percentage

This formula allows you to find out how much you will spend in total after applying any discounts and adding taxes.

Example:

  • Price per Pair (§ P §): $10
  • Number of Pairs (§ N §): 3
  • Discount (§ D §): 10%
  • Tax (§ T §): 5%

Total Cost Calculation:

§§ TC = (10 × 3) × (1 - 10/100) × (1 + 5/100) = 30 × 0.90 × 1.05 = $28.35 §§
