john and his three brothers share a cell phone plan. the cell phone company charges a flat rate of $90 per month, which of the four brothers share equally. In addition, the cell phone company charges 25 cents per megabyte of data download. Each brother pays for his own downloaded data. John's share of the current cell phone bill is $147.50. which equation determines how many megabytes of data john downloaded?

A. 90+0.25x=147.50
B. 90x+0.25=147.50
C. 22.5+0.25x=147.50
D. 22.5x+0.25=147.50

ok...so u have 4 people sharing this plan...they each pay for their own data..however, the $ 90 flat rate is split between them equally.
90/4 = 22.5....so each of them pay 22.50 each for the flat rate.

so John's equation is : 22.5 + 0.25x = 147.50

The linear equation which expresses John's share of the data fee is 22.5 + 0.25x = 147.50

Outline of charges :

Flat fee = $90
Flat fee paid by John = (90 ÷4) = $22.5
Charge per megabyte = 25 Cent = $0.25
John's total share = $147.50

John's total charges can be calculated thus :

Flat fee share + (cost per megabyte × number of megabytes) = total charge

Let; number of megabyte = x

22.5 + 0.25x = 147.50

Therefore, the equation which expresses John's share is 22.5 + 0.25x = 147.50
