Mrs. Cason gives her class a spelling quiz every Monday, a math quiz every other Monday and a history quiz every third Monday . Sally smarty is in Mrs. Carson's class. She received a grade of 100% on all three quizzes today. How long will it be before she again has to take all three quizzes in on day?

well it will be history in three weeks, and a spelling quiz. In six weeks, history, math, and spelling. I think. Check that.

figure it out your self
