A cell phone company charges $60.00 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?

1) c=60-0.05d

2) c=60.05d

3) c=60d-0.05

4) c=60+0.05d

Verified Answer :

A cell phone company charges $60.00 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 uses and c represents the total charges at the end of the month, Option C = 60 + 0.05d is the linear equation that can be used to determine a user's monthly bill.

the answer is 4) c=60+0.05d  that's how you would set ti up
