Batch setup times are negligible. The flowchartdenotes the path each product follows through the manu-facturing process, and each product’s price, demand perweek, and processing times per unit are indicated as well.Purchased parts and raw materials consumed during pro-duction are represented by inverted triangles. CKC can makeand sell up to the limit of its demand per week; no penaltiesare incurred for not being able to meet all the demand. Eachworkstation is staffed by a worker who is dedicated to workon that workstation alone, and is paid $6 per hour. Totallabor costs per week are fixed. Variable overhead costs are$3,500/week. The plant operates one 8-hour shift per day, or40 hours/week. Which of the three workstations, W, X, or Y,has the highest…Kiko Teddy Bear is a manufacturer of stuffed teddy bears.
