mollys basic cell phone plan charges $35.99 for service plus $0.2 per minute beyond the included 250 minutes in the plan. how much will it cost molly if she used her cellphone for 440 minutes in one month
$35.99 includes 250 'free' minutes. anything over that is $0.2 per minute. So if she used 440 total minutes that means 440 minus 250 free minutes = 190 minutes over. 190 minutes times $0.2/minute = $38 extra
