The Porters’ food, clothing, and medical expenses are variable expenses. Theses are expenses that vary from month to month. This is because the Porters’ won’ spend the same exact amount on food, clothes, and medical expenses every month. One month, Mrs. Porter may have broken her arm, but the next month she didn’t. This is a variable cost because one month she has medical expenses, and the next month she didn’t. One month Mr. Porter needed a suit and tie for a job interview, but the next month he didn’t need to buy any new clothes. One month the Porters’ threw a party a had to buy a ton of food, the next month they didn’t buy a lot of food.
Hope made sense and hope this helps :)
