To save money, Branded company Cheese will reduce each dimension of its rectangular box container (which is entirely full of cheese) by 50%, and reduce the price it charges its consumers by 50% as well. By what percentage does this increase the price-per-cubic-inch that each consumer will pay for cheese? Choose the correct choice from the following answers:	A) 1. No change	B) 2. 50%	C) 3. 100%	D) 4. 200%	E) 5. 300%
If the current volume is L * W * H, then the new volume is 12 (L) * 12 (W) * 12 (H), or 18 * LWH. So the new portion is 1/8 the size of the old portion. But the new cost is only ½ the cost, meaning that if the old price-per-unit was 1:1, now it’s 12 : 18, or 4:1. So the consumer is paying 400% of what it used to, or 300% more than it used to. The answer is therefore 5. 300%.
