Bradley and Ryan are having a contest to see who can collect the most bumper stickers. Bradley started with 23 stickers and plans to add 4 each month. Ryan has 9 stickers and plans to add 6 each month. After how many months will they have the same number of bumper stickers?
Well we can make one of those t charts, so start with 23 and 9, then add 4 to the 23 and 6 to the 9 until they match. In this case it would be 5 Months, I am assuming it is D and that instead of 51 it should be 5
