Joachim wants to know if he can afford to add texting to his cell phone plan. He currently spends $21.49 per month for his cell phone plan, and the most he can spend for his cell phone is $30 per month. He could get unlimited text messaging added to his plan for an additional $10 each month. Or, he could get a “pay-as-you-go” plan that charges a flat rate of $0.15 per text message. He assumes that he will send an average of 5 text messages per day. Can Joachim afford to add a text message plan to his cell phone plan?
