Practice : We would like to buy a refrigerator for our new corner-shop that has more 50% more capacity than our current refrigerator (which cost $1000). The appropriate power sizing exponent for this type of equipment is 0.725. Use the power-sizing model to estimate the cost of this new refrigerator! Answer : Dik : - Old refrigerator = $ 1000,- New refrigerator = kapasitasnya 50 % lebih banyak dari kulkas lama -x = 0,725 Dit : menggunakan power-sizing model, harga kulkas baru = $... Penyelesaian : Misalkan, Capacity of old refrigerator = 1 Maka, capacity of new refrigerator = 50% lebih banyak dari capacity of old refrigerator = 0,5 + capacity of old refrigerator = 0,5 + 1 = 1,5 Maka, 𝑐𝑜𝑠𝑡 𝑜𝑓 𝑛𝑒𝑤 𝑟𝑒𝑓𝑟𝑖𝑔𝑒𝑟𝑎𝑡𝑜𝑟 = 1,341733 ($ 1000) 𝑐𝑜𝑠𝑡 𝑜𝑓 𝑛𝑒𝑤 𝑟𝑒𝑓𝑟𝑖𝑔𝑒𝑟𝑎𝑡𝑜𝑟 = $ 1341,733 ~ $ 1.342,- (pembulatan) Maka, harga dari kulkas baru = $ 1.342,-
