John and his three brothers share a cell phone plan. The cell phone company charges a flat rate of $90 per month, which the four brothers share equally. In addition, the cell phone company charges 25 cents per megabyte of data downloaded. 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

C

Step-by-step explanation:

90/4 is 22.5 so one brother pays $22.5 of the flat fee. Because we don't know the number of megabytes John used, and one megabyte is 0.25, that would make is 0.25x.

so the equation it 22.5+0.25x = 147.50

according to egenuity the answer is

step-by-step explanation:

d. 344.22

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
