Answer:
cost of 240 for 8 kg
150 buys 5 kg
Step-by-step explanation:
unit cost = cost/weight
unit cost for 6 kg for 180:
unit cost = 180 / 6 kg = 30/kg
cost = unit cost × weight
cost for 8 kg = 30/kg × 8 kg = 240
cost = unit cost × weight
Solve for weight:
weight = cost/unit cost
Weight you can buy with 150
weight = cost/unit cost
weight = 150/ (30/kg)
weight = 5 kg
