Question

Cell-Phone-R-Us offers a phone plan for $26 per month after a start-up fee of $215. If Caleb spent a total of $839, how many months of service did he pay for?

Answer 1

Answer:

24 months

Step-by-step explanation:

1. 839=26x+215
2. Move 839 to the other side
3. -26x=215-839
4. subtract
5. -26x= -624
6. divide by 26
7. x=24

Answer 2

Answer:

Caleb has paid for 24 months of service.

Step-by-step explanation:

1) based on what is written in this problem, setup an equation.

26x + 215 = 839

2) Subtract 215 from both sides.

839 - 215 = 624

3) 26x = 624

Divide both sides by 26

624/26 = 24

Answer: Caleb has paid for 24 months of service.
