Answer:

Step-by-step explanation:

I think your question is to write WRITE A SYSTEM OF EQUATIONS in that situation.

And here is my answer:

  • Let y = the total cost
  • Let m - the number of minutes

1. The first choice is to pay $10.00 per month plus &0.09 per MB of data

<=> y = 0.09m + 10  

2. The second choice is to pay $16.00 per month plus $0.07 per MB of data

<=> y = 0.07m + 16

So the system of equation is:

[tex]\left \{ {{y=0.09m + 10 } \atop {y=0.07m + 16}} \right.[/tex]

Hope it will find you well.
