1. The problem asks us to find the tip amount Mia gives to the movers based on a 16% tip rate on a $500 service charge. 2. The formula to calculate a tip is: $$\text{Tip} = \text{Service Charge} \times \text{Tip Percentage}$$ 3. Important rule: The tip percentage must be converted from a percentage to a decimal before multiplying. To convert 16% to decimal, divide by 100: $$16\% = \frac{16}{100} = 0.16$$ 4. Now substitute the values into the formula: $$\text{Tip} = 500 \times 0.16$$ 5. Multiply to find the tip: $$\text{Tip} = 80$$ 6. Therefore, Mia tips the movers 80.
