The J8B Card Shop sels calendars featuring a different colonial picture for each month. The once-a-year order for each year's calendar arrives in September. From past experience, the September-to-uly demand for the calendars can be approximated by a normal distribution with u 290 and standard deviation- 20. The calendars cost $8.50 each, and JAB sels them for $19 each. Use Appendix A to determine z-value. Round z-value to two decimal places. Do not round any other intermediate calculations. Round your answers to the nearest whole number. a. Suppose that 368 throws out all unsold calendars at the end of July. Using marginal economic analysis, how many calendars should be ordered? calendars b. If JA selis surplus calendars for $4 at the end of July and can sell all of them at this price, how many calendars should be ordered? calendars
