Using an **exponential **function, it is found that Erina will run **490.5 yards** each day in the third week of her training.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

In which:

**A(0) **is the initial value.

**r **is the growth rate, as a decimal.

In this problem:

**200 meters **each day during the **first week** of her training, hence .

- Erina's training goal is to run
**150%** of the distance she ran each day in the previous week, hence

Then, the **equation **is:

In the **third week**, the daily distance in meters that she runs is:

Since there approximately 27.34 yards in 25 meters, we apply the **proportion**:

Erina will run **490.5 yards** each day in the third week of her training.

If it has an 80% chance to land on time then it has a 20% chance it will not so the probability that it wont is 20/100 or 1/5, 0.20, or 20%. **Explanation: **100% minus 80% would lead to 20%.

**Answer:**

The answer is D) 4y-4.
