Question

A cell phone cost $10 for the phone and $2 per hour that someone talks on the phone. If Jeremiah spent $30 total, how many hours did he spend talking on the phone? Write an equation to represent this situation.
A. 10-2h=30
B. 10(2h)=30
C. 10 + 2h=20
D. 10+30=h​

Answer 1

Answer: C. 10 + 2h = 30

Step-by-step explanation:

1. A does not make sense because the phone billing company would not be cutting off the money they earn while Jeremiah is on a call with someone.
2. B does not make sense because the phone billing company would be charging Jeremiah a higher amount than the amount he uses while speaking on the phone.
3. C makes sense because the phone billing company charges Jeremiah the total amount of his phone and $2 per hour he is on a phone call with someone.
4. D does not make sense because the total is 30 not h.
