Amy types at an average speed of 38 words per minute. She has already typed 1,450 words of her final paper, which will be more than 4,000 words. Which inequality can be used to solve for x, the number of minutes it will take Amy to finish typing her paper?

D. 38x + 1,450 > 4,000

Step-by-step explanation:

A. 38x − 1,450 > 76

B. 38(x + 1,450) > 4,000

C. 38x > 4,000

D. 38x + 1,450 > 4,000

Let

x = number of minutes it will take Amy to finish typing her paper

Amy types at an average speed of 38 words per minute

That is, it will take Amy 38x minutes to type her final paper

She has already typed 1,450 words

Amy wants to type her final paper, which will be more than 4,000 words

That is > 4,000

The inequality is

38x + 1,450 > 4,000

The correct answer is

D. 38x + 1,450 > 4,000

f is the midpoint of

they would have to work 32 hours.
