1. **State the problem:** We need to find how many milligrams of vitamin C are in 1 serving of orange juice and cranberry juice. 2. **Formula:** To find the amount of vitamin C per serving, use the formula: $$\text{Vitamin C per serving} = \frac{\text{Total vitamin C}}{\text{Number of servings}}$$ 3. **Calculate for orange juice:** $$\frac{750}{6} = 125$$ So, orange juice has 125 mg of vitamin C per serving. 4. **Calculate for cranberry juice:** $$\frac{135}{1.5} = 90$$ So, cranberry juice has 90 mg of vitamin C per serving. 5. **Complete the statement:** Orange juice has 125 mg of vitamin C per serving. Cranberry juice has 90 mg of vitamin C per serving.
