Answer:

96 chocolate bars

Step-by-step explanation:

If Brian sold 25% of his chocolate bars and now he's left with 72, let's subtract 25% from 100%.

100% - 25% = 75%

Now, let's set up the equation & solve:

1. Set up Equation

  • 75/100 = 72/x

2. Cross-Multiply

  • 75/100 = 72/x
  • 75 · x = 72 · 100
  • 75x = 7200

3. Divide both sides by 75

  • 75x = 7200
  • 75x/75 = 7200/75
  • x = 96

Therefore, Brian started with 96 chocolate bars.

100% - 25% = 75%

[tex]\frac{75}{100}[/tex] = [tex]\frac{72}{x}[/tex]

x = [tex]\frac{100*72}{75}[/tex] = 96 bars
