On april 11, millie bought a lawn mower with a 50-day guarantee. if the guarantee begins on the date of purchase, what is the first dsy on which the mower will no longer be gua
May 22nd would be the first day because thirty days is one month and one month from April 11th is May 11th and then 20 days after is May 21st which is when the guy ends so the first day is May 22nd
