You are trying to pack for an overseas trip you have a weight limit for your checked bag and need to know how much everything weighs in order to help narrow things down. you are bringing shoes (s), regular clothes (r), and coats (c), and the expression 2.5s + r+ 3c+ 5 represents the total weight. In pounds, of your packed suitcase. SO if you bring 2 pairs of shoes, 10 items or regular clothes, and 2 coats, how much will your bag weigh?
