Thank you for the opportunity to help you with your question!

Since Michael put in 70*11 dollars after 11 months and had 1250 in his account, that must mean had 1250-70*11 dollars in his account initially. He originally had 480 dollars, then added 70 dollars for x months. This equation is y=480+70x

The correct answer is c, as it is the only equation that, when expanded, equals y=480+70x
