A cell phone company charges $60 a month for up to 1 gigabyte of data. The cost of additional data is $0.05 per megabyte. If d represents the number of additional megabytes used and c represents the total charges at the end of the month, which linear equation can be used to determine a user's monthly bill?

Respuesta :

Answer:[tex]c=60+0.05d[/tex]

Step-by-step explanation:

Given

Company charges [tex]\$60[/tex]  for  [tex]1\ GB[/tex] data

and charges [tex]\$0.05/MB[/tex]

If c is the total cost and d represent no of additional megabyte then

Cost is given by the sum of fixed price + additional data charge

[tex]c=60+0.05\times d[/tex]

Therefore final charge is given by

[tex]c=60+0.05d[/tex]
