A phone company charges $67 for monthly access and $14 for each gigabyte of data used. If you sign a two-year contract and use 147.5 gigabytes of data, what is the total amount you will pay for phone service?

the answer is below :)

Step-by-step explanation:

BigBytes will be 100 +10x = y ($100 flat fee plus 10 times the number of gigabytes equals total cost).

GoGig will be 120 + 5x = y.  ($120 flat fee plus 5 times the number of gigabytes equals total cost).

Now set them equal to each other and solve for x to find where the gigabytes are the same.

100 + 10x = 120 + 5x

Subtract 100 from both sides:  10x = 20 + 5x

Subtract 5x from both sides:  5x = 20.

Divide both sides by 5:  x = 4.  4 gigabytes is the answer.

a brainliest would be appreciated :)

how is that middle school

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
