Example 2­3e: Page 389 Example 4f: Page 389 Example 5g: Page 390 Write in simplest form: 2g – 3 + 11 – 8g Write an expression in simplest form for the cost of the jacket in example 4 if the markup is 8%. Then determine the total cost after the markup. You have some money. Your friend has $50 less than you. Write an expression in simplest form that Example 4: The original cost of the jacket is $35. represents the total amount of money you and your friend have. Summary:
