Question

A prepaid phone card has a balance of $22.40 remaining. If calls are $0.035 per minute, which equation represents the number of minutes, m, you may talk using the card?

Your answer: witch one is it



m/0.035 = 22.40


22.40m = 0.035

m/22.40 = 0.035


0.035m=22.40

Answer 1

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

Explanation:

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`

⇒
`((0.035)m)/(0.035) = (22.40)/(0.035)`

⇒
`m= (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` .
