One of the requirements for becoming a court reporter is the ability to type 225 words per minute. Donald can currently type 180 words per minute, and believes that with practice he can increase his typing speed by 5 words per minute each month. Which of the following represents the number of words per minute that Donald believes he will be able to type m months from now?

Options

A. 5 + 180m
B. 225 + 5m
C. 180 + 5m
D. 180 - 5m

Explanation

To find the number of words per minute that Donald believes he will be able to type \( m \) months from now, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Current Typing Speed**:
Donald can currently type 180 words per minute.

2. **Determine Monthly Increase**:
He believes he can increase his typing speed by 5 words per minute each month.

3. **Calculate Increase Over \( m \) Months**:
After \( m \) months, the total increase in his typing speed will be \( 5 \times m \) words per minute.

4. **Formulate the Expression**:
To find his typing speed after \( m \) months, we add the current speed to the total increase:
\[ \text{Typing Speed after } m \text{ months} = 180 + 5m \]

5. **Conclusion**:
The expression that represents the number of words per minute that Donald believes he will be able to type \( m \) months from now is:
\[ 180 + 5m \]
