**Alcohol** After a large number of drinks, a person has a blood alcohol level of200 mg/dL (milligrams per deciliter). If the amount of alcohol in the blood decays exponentially, and after 2 hours, 112.5 mg/dL remain, find an exponential model for the person's blood alcohol level, and use your model to estimate the person's blood alcohol level after 4 hours. **[HINT:** See Example 2.**]**

To determine

**To calculate:** The exponential model for the person’s blood alcohol level and estimate the level after 4 hours if the amount of alcohol in the blood decays exponentially from

Explanation

**Given Information:**

The initial blood alcohol level is

**Formula used:**

Formula of exponential function is given by,

**Calculation:**

Consider the formula of exponential function,

Here

Initially blood alcohol level was

Substitute

Substitute

Now, The amount of alcohol in the blood decays exponentially from
