The cost of transporting 80 bags of cement, each weighing 50 kgs, is $6000. What's the cost of transporting three times as many cement bags, each weighing 3/5 times as many kgs? Give me reasons, before answering the question
Three times as many cement bags is 3 * 80 = 240 cement bags. If a bag of cement weighs 50 kg, 3 / 5 times as much weight is 3 / 5 * 50 = 30 kgs. If the cost of transporting 80 bags of cement, each weighing 50 kgs, is $6000, the cost of transporting one bag of cement weighing 50 kg is $6000 / 80 = $75. Since a bag weighing 50 kgs costs $75 to transport, a bag weighing 30 kgs will cost 30 * $75 / 50 = $45 to transport. The cost of transporting 240 cement bags each weighing 30 kgs is $45 * 240 = $10800. So the final answer is 10800.
