Does bread lose its vitamins when stored? small loaves of bread were prepared with flour that was fortified with a fixed amount of vitamins. after baking, the vitamin c content of two loaves was measured. another two loaves were baked at the same time, stored for one day, and then the vitamin c content was measured. in a similar manner, two loaves were stored for three, five and seven days before measurements were taken. the units are milligrams per hundred grams of flour (mg/100 g). here are the data.

Special order carson manufacturing, inc., sells a single product for $36 per unit. at an operating level of 8,000 units, variable costs are $18 per unit and fixed costs $10 per unit. carson has been offered a price of $20 per unit on a special order of 2,000 units by big mart discount stores, which would use its own brand name on the item. if carson accepts the order, material cost will be $3 less per unit than for regular production. however, special stamping equipment costing $4,000 would be needed to process the order; the equipment would then be discarded. assuming that volume remains within the relevant range, prepare an analysis of differential revenue and costs to determine whether carson should accept the special order. use a negative sign with answer to only indicate an income loss from special order; otherwise do not use negative signs with your answers.
