I need help solving this problem:

Kenny and Jannah want to purchase a car so that Kenny doesn't have to take the bus up their local mountain where Kenny works as a ski shop manager in the winter and a mountain bike shop manager in the summer. Jannah, who drives for Lyft, already owns a 2010 PT Cruiser. Kenny complains that the mildewy bus is cold and gross. For the past six years they have been able to put $50 each month into a savings account with an APR of 1.2%.

a) How much do Kenny and Jannah have saved toward a down payment? Indicate which formula you use and identify all of the relevant variables (A, P, APR, n, Y, and/or PMT).
