You have to choose a cell phone plan that is least expensive in a month plan a is a flat rate $50 per month unlimited data plan B is $0 per month but you have to pay $5 per gigabyte of data used if you average about 6 GB of data per month which option would be least expensive

To compare the cost of the two cell phone plans, let's calculate the cost for each option based on your average monthly data usage of 6 GB:

Plan A (flat rate $50 per month):
The cost would be a constant $50 per month, regardless of the amount of data used.

Plan B ($0 per month + $5 per GB):
For 6 GB of data, you would have to pay 6 GB * $5/GB, which equals $30.

Now comparing the costs:
- Plan A: $50 per month
- Plan B: $30 per month

In this scenario, Plan B would be the least expensive option, costing $30 per month compared to Plan A's $50 per month.

To determine which option is least expensive, you need to calculate the cost for each plan based on your average data usage of 6 GB per month.

Option A:
Flat rate: $50 per month

Option B:
Data usage: 6 GB
Cost per GB: $5

To calculate the cost for option B, multiply the data usage (6 GB) by the cost per GB ($5):
Cost for option B: 6 GB * $5/GB = $30

Comparing the costs:
Option A: $50 per month
Option B: $30 per month

In this case, option B is the least expensive as it will cost you $30 per month compared to the flat rate of $50 per month for option A.
