Short And Extra Answer

                           Hello everyone today I am going to tell you the answer.
                           Step 1: 60 times 2 because I am going to assume that there are all two-buttoned coats.        60 * 2 = 120
               Step 2: 82 subtracted from 120 so we can find how much we are short off. 120 – 82 = 38
               Step 3: 2 subtract 1 so we can find the difference of buttons of the two-buttoned coat and the one-buttoned pants. 2 – 1 = 1
               Step 4: 38 divided by one next is to get the total number off one-buttoned pants and       one-buttoned skirt. 38 / 1 = 38
               Step 5: 38 divided 2 to get  the number of pants. 38 / 2 = 19
               Hope you got it right. :)
