Question

List of reading his cell phone and monthly service please try and sell offers a new phone for $50 in unlimited service for a monthly fee of $40 cellular offers a new phone and unlimited service for a monthly fee of $50 after how many months will the cost of the two phones and monthly service bethe same

Answer 1

After 5 months the cost of the two phones and monthly service be the same.

Explanation:

1st service cost = $50 + $40x, where "x" represents the number of months

2nd service cost = $50x

Now we have to find the number of months the cost of the two phones and monthly service be the same.

Now we have to equivate and find the value of x.

50x = 50 + 40x

Subtracting 40x from both sides, we get

50x - 40x = 50 + 40x - 40x

10x = 50

Dividing both sides by 10, we get

x = 50/10

x = 5

After 5 months the cost of the two phones and monthly service be the same.

Hope you will understand the concept.

Thank you.
