if we assume that she had exactly 200 dollars mone per shirt times amount of shirts=amount spent if we assume that she spend 200 dollars then 15 times ?=200 divide both sides by 15 ?=13.3333333333333 if she had spent 200 exactly she could have bought 13.333 shirts you can't buy 0.3333 shirt so round down 13 shirts bought that is assuming she had at least 195 to spend if she spent 0 dollars (which is less than 200) then she bought 0 shirts, that is also possible
