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
