Question

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?

Answer 1

Answer:

(147.50 - 22.5)/.25

Step-by-step explanation:

First subtract his portion of the $90. Which is $22.5, when subtracted from 147.5 you get $125. Now divide $125 by .25 cents and you get the amount of megabytes he downloaded.

Answer 2

Answer: 22.5+0.25x=147.50

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

• Flat rate: $90, (share equally among the four brothers means 90/4 =$22.5 each)
• Cost per megabyte: $0.25
• John's share: $147.50

So, the equation is

22.5+0.25x=147.50

Where "x" is the number of megabytes of data that john downloaded
