Question

Maria has a cell phone and she gets charged for data each month. She is

thinking about paying a flat fee $70. If the cost for 1 GB is $12.5, how much would
she save if she uses 8 GB for one month?

Answer 1

If it costs $12.5 for every GB and we use 8 then 12.5*8=$100. So if our flat rate now is $70 we would loose 100-70=$30

So Maria would loose $30 a month if she pays per GB
