Question

Although not so common now, consider a phone plan that does not have unlimited texting. Your base plan costs you $30 a month and each text sent or received is only 12 cents. Write an equation to describe the total monthly cost of your bill with x text messages and y cost in dollars.

Answer 1

Answer:

$y=.12x+30$

Step-by-step explanation:

The total cost would be "Y".

"x" is would be "per text message".

12 cents per text message would be .12x.

And then, on top of that, we have to pay $30 per month. ( + 30 )

Put together, the equation should be y =  .12x + 30.
