To save money, Arkadelphia Cream Cheese will reduce each dimension of its rectangular box container (which is entirely full of cream cheese) by 75%, and reduce the price it charges its consumers by 75% as well. By what percentage does this increase the price-per-cubic-inch that each consumer will pay for cream cheese?
Answer/Solution
5. 1500%
Steps/Work
L = 20: B = 10: H= 10 of initial box and Price = 100$
Therefore Price / cubic inch = 100 / (20*10*10) =0.05
Now, when dimensions are reduced by 75% and price also reduced by 75%
L = 5; B=2.5; H=2.5 and Price = 25$
Therefore price / cubic inch = 25 / (5*2.5*2.5) =0.8
Percentage change = (0.8 - 0.05) *100/ 0.05 = 1500%
Answer is E
