Answer 2

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

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
