Question

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?

Answer 1

Answer:$c=60+0.05d$

Step-by-step explanation:

Given

Company charges $\ 60$  for  $1\ GB$ data

and charges $\ 0.05/MB$

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

$c=60+0.05\times d$

Therefore final charge is given by

$c=60+0.05d$
