Answer:
The systems of equation for the amount spent are as follows
Step-by-step explanation:
In this problem we are expect to give a model or an equation that represents the amount of money spent per month given a fix subscription amount and a variable fee which is based on extra minutes spent.
let Y represent the amount of money spent in total for the month
The first case:
Subscription =$5
charges per minutes = $0.99
therefore the amount spent can be modeled as
The second case:
Subscription =$10
charges per minutes = $0.79
therefore the amount spent can be modeled as
