Answer 1

If Imran borrows $4 per week, then after x weeks he will borrow 4x dollars

Imran has a debt greater than $50, then:

4x > 50

Dividing by -1 at both sides (note that the sign changes):

-4x < -50

Therefore, the correct choice is D.

To find for how many weeks he could have been borrowing, we need to solve the inequality for x.

4x > 50

x > 50/4

x > 12.5

He could have been borrowing for more than 12 and a half weeks
