The amount which Autumn would have to pay if she used 3GB past over the limit is; $80. The amount which Autumn would have to pay if she used 2GB past over the limit is;$70
What is mathematical expression?
A mathematical expression is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division.
here, it is to find the amount of money Autumn has to pay if she used 3 GB  and 2GB past the limit.
Hence, it follows that she has to pay; $50 +$10 x (number of GB used over the limit) since it takes $10 per GB over the limit. Ultimately, the amount paid for 3GB past the limit is;$50 + $30 =$80.
and,
The amount paid for 2GB past the limit is : $50 +$20 = \$70.
