Correct option D) $(0.035)m = 22.40$ .

<u>Step-by-step explanation:</u>

Here we have , A prepaid phone card has a balance of $22.40 remaining. Given that it costs $0.035 per minute . We need to find an equation represents the number of minutes, m, you may talk using the card . Let's find out :

Total balance = $22.40

It costs $0.035 for one minute of call . Let's suppose that with balance $22.40 we can talk for m minutes . So equation will be :

⇒ $(0.035)m = 22.40$

⇒ $\frac{(0.035)m}{0.035} = \frac{22.40}{0.035}$

⇒ $m= \frac{22.40}{0.035}$

Therefore , an equation represents the number of minutes, m, you may talk using the card is $(0.035)m = 22.40$ . Correct option D) $(0.035)m = 22.40$ .
