- Already got wrong Chatgpt answer Plz don't use chat gptarrow_forwardMany artists and art lovers embrace the idea of the “starving artist,” such as the early career artist who hasn’t yet sold much of her art or whose art hasn’t yet been “discovered,” the artist who sacrifices lifestyle, living in a cheap apartment in a poor neighborhood, scraping by with barely enough to eat, pouring every dollar at their disposal into his art, or the artist who makes do by working other jobs, such as a waiter or waitress, to pay the rent so he can work on his art in his free time. As an artist and businessperson, however, you’d rather not be a “starving artist.” Of course, it takes time to master your art, display your work, and build a following, but is it necessary if you’re successful as an artist to also be a bad businessperson. The challenge with your art, bronze sculptures, however, is what comes first, the chicken or the egg, in other words, success as an artist or financial success. With the cost of materials, foundry time to pour and shape your creations,…arrow_forwardCan you guys help me with this? Thank you!

- Identify the causes of the problem. -Start by Reviewing the Inputs box in the Organizing Framework to help you identify the causes of the problem in this case. First identify the person factors and then situation factors as inputs. -Then move to the Processes box in the Organizing Framework and review the potential causes among individual level, team level and organizational level factors. -For each cause explain why this is a cause of the problem. For each cause ask yourself “why” is this a cause to the problem we identified. Remember that asking why multiple times will help you find the root cause of the problem.arrow_forward6.

Finally, each unit of U requires 2 units of Y and 3 units of Z. One firm manufactures all items. It takes 2 weeks to make S, 1 week to make T, 2 weeks to make U, 2 weeks to make V, 3 weeks to make W, 1 week to make X, 2 weeks to make Y, and 1 week to make Z.

WestJet’s daily flight from Edmonton to Toronto uses a Boeing 737, with all-coach seating for 120 people. In the past, the airline has priced every seat at $140 for the one-way flight. An average of 80 passengers are on each flight. The variable cost of a filled seat is $25. Katie Morgan, the new operations manager, has decided to try a yield-revenue approach, with seats priced at $80 for early bookings and at $190 for bookings within one week of the flight. She estimates that the airline will sell 65 seats at the lower price and 35 at the higher price. Variable cost will not change. Which approach is preferable to Ms. Morgan?arrow_forward2. A large Saskatchewan feed mill, B. Swart Processing, prepares its sixty-month aggregate plan by forecasting demand for 50-pound bags of cattle feed as follows: January, 1000 bags; February, 1200; March, 1250; April, 1450; May, 1400; and June, 1400. The feed mill plans to begin the new year with no inventory left over from the previous year, and backorders are not permitted. It projects that capacity (during regular hours) for producing bags of feed will remain constant at 800 until the end of April, and then increase to 1100 bags per month when a planned expansion is completed on May 1. Overtime capacity is set at 300 bags per month until the expansion, at which time it will increase to 400 bags per month. A friendly competitor in Alberta is also available as a backup source to meet demand—but can provide only 500 bags total during the six-month period. Develop a six-month production plan for the feed mill using the transportation method. Cost data are as follows: Regular-time…arrow_forward
