2. John is thinking about buying a letter jacket for $180.00. Dry cleaning the jacket would cost about $10.00. John estimates he
would have the jacket cleaned six times a year.
How many years could John wear the jacket before cleaning costs would equal the purchase price?
What would his total investment be after this amount of time?
How many times would John have to wear the jacket to make the cost per wear $5.00 or less?
Trial and error mainly, but I would at least change the settings for night time and maybe change the white balance to make it look normal (so it isn't yellow or blue). It's mainly up to the person to decide what is correct for the exposure time and color balance.
