Cell phone plan a charges $20 per month plus $2 per gigabyte of data. cell phone plan b
charges $15 per month plus $3 per gigabyte of data. how much data would you need to use
for the monthly charges to be the same?
a)
7

b)
6

c)
5

d)
4

The amount of Data needed for monthly charge to be same = 5 GB

Step-by-step explanation:

Given as :

Cell Phone plan A

Monthly rent of $ 20 per month

The charge on use of Data is $2 per GB

Cell Phone plan B

Monthly rent of $ 15 per month

The charge on use of Data is $3 per GB

Now from given two data plan ,

To make the monthly charge on Internet for both the cell phone to be same

Let the amount of data needed be x GB

So, A|C to question :

20 + x × 2  = 15 + x × 3

Or, 20 - 15 = (3x - 2x)

Or, 5 = x

∴ x = 5 GB

Hence The Amount of Data needed to make charges same is 5 GB Answer

step-by-step explanation:

trshd h rdhsjsdrnytjdt jyjyukfddythj

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
