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 witch one is it

m/0.035 = 22.40

22.40m = 0.035

m/22.40 = 0.035

0.035m=22.40

Correct option D) .

Step-by-step 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 :

⇒

⇒

⇒

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

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
