Answer:25 months

Step-by-step explanation: Let's make the equations first,

Plan A: 70x   Plan B: 50x+500

Now we make it into an equivalent equation:

70x=50x+500

Then we solve:

70x=50x+500

-50x -50x

20x=500

÷20 ÷20

x=25

To check if it's correct, we just plug it in:

70(25)=50(25)+500

1750=1750

The number of months should be 25.

  • The calculation is as follows:

Plan A: 70x  

Plan B: 50x+500

Now we have to make the equivalent equation

70x=50x+500

70x - 50x = 500

20x = 500

x = 25

 

Therefore we can conclude that The number of months should be 25.
