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. Do not use spaces for your answer. ______________________________ In one month 217,000 messages were sent between two brothers in Philadelphia. What was their approximate bill?
