§03Practical Example

Step-by-step walkthrough

Scenario

Apply the formula to a realistic set of inputs: Units sold = 100, Price per unit ($) = 25.

  1. 01Start by noting the input — Units sold: 100.
  2. 02Start by noting the input — Price per unit ($): 25.
  3. 03Substitute these values into the formula: e.units × e.price
  4. 04Compute Total sales: the calculator returns 2500.
  5. 05Cross-check the answer by opening the Derivation panel above — every line of math is shown so you can follow the computation end-to-end.

Common Sales Problems

The formula gets rearranged depending on which variable you need. Here are the patterns you’ll run into in the real world — find the one that matches your problem and follow the worked steps.

01 · PATTERN

Units sold halved

units = 50 (from 100)

Keep every other input at its default and halve the units sold. See how total sales responds.

  1. 01New Units sold: 50
  2. 02Baseline Total sales: 2500
  3. 03New Total sales: 1250
  4. 04Total sales decreases by 50% → use this sensitivity to plan for real-world variation.
02 · PATTERN

Units sold doubled

units = 200 (from 100)

Keep every other input at its default and double the units sold. See how total sales responds.

  1. 01New Units sold: 200
  2. 02Baseline Total sales: 2500
  3. 03New Total sales: 5000
  4. 04Total sales increases by 100% → use this sensitivity to plan for real-world variation.
03 · PATTERN

Price per unit ($) halved

price = 12.5 (from 25)

Keep every other input at its default and halve the price per unit ($). See how total sales responds.

  1. 01New Price per unit ($): 12.5
  2. 02Baseline Total sales: 2500
  3. 03New Total sales: 1250
  4. 04Total sales decreases by 50% → use this sensitivity to plan for real-world variation.
04 · PATTERN

Price per unit ($) doubled

price = 50 (from 25)

Keep every other input at its default and double the price per unit ($). See how total sales responds.

  1. 01New Price per unit ($): 50
  2. 02Baseline Total sales: 2500
  3. 03New Total sales: 5000
  4. 04Total sales increases by 100% → use this sensitivity to plan for real-world variation.
