This brief "Math for Real" article introduces Ohanna, a seventh grader who lives in New York City and regularly takes the bus to get around the city. Ohanna pays $2.50 per bus ride when using her MetroCard. She earns a 5% bonus when she refills the card with a minimum of $5.00. For example, if she adds $10.00 on her MetroCard, her balance would actually be $10.50 because $10.00 + $0.50 (5% bonus) = $10.50. However, on March 22, 2015, the New York Metropolitan Transportation Authority (MTA) announced an increase. The changes will require Ohanna to analyze her trip costs. Her analysis is presented in this article.
