With the help of a family friend, seventeen-year-old Freed DeLuca opened the first SUBWAY store in 1965. DeLuca believed in using only the freshest ingredients and drove many miles each week in his Volkswagen bug to buy fresh produce. Later management decided to "give back" to the community and now supports research related to both heart disease and cancer. The firm differs from many other fast-food firms by offering healthy, fresh foods.
Profit margins are surprisingly small in most businesses, so managers must work very hard to control costs. A primary responsibility of a store manager at SUBWAY is to control costs. Of course, the store manager is also responsible for many issues related to employees, the quality of food and service, and also sales.
Fernandez notes that meat and cheese costs went up from $1864.92 last week to $2065.48 this week and attributes it to additional customers. Find the difference between the two. If the average cost of meat and cheese per sub sandwich is $.94, estimate the number of additional customers this week compared to last week, rounded to the nearest whole number.
