Question

The phone company offers to long-distance plans the first charges a flat value of five dollars per month plus $.99 each minute used and the second charge is $10 a month plus $.79 for each minute used if X represents the number of minutes use each month which system each of equations represent the amount of money why are you spin

Answer 1

The systems of equation for the amount spent are as follows

`Y= 0.99x+5`

`Y= 0.79x+10`

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

`Y= 0.99x+5`

The second case:

Subscription =$10

charges per minutes = $0.79

therefore the amount spent can be modeled as

`Y= 0.79x+10`
