Question

Hi i really need help 

Answer 1

Hi Billy,

 

If one text message costs $0.15 and there is a base cost of $9 per month, then the total cost should be:

 

0.15 * x + 9

 

Hope this helps!

Answer 2

The monthly cost will be the monthly cost of the plan + the total cost of the texts in a month. The total cost of texts in a month is .15 * x = .15x. Therefore, the total monthly cost is:

 

9 + .15x
