Gary works in a cabinet shop and loves helping customers fall in love with their remodeled kitchens and bathrooms. Knowing that his craftsmanship is a big part of their homes, he takes his work very seriously. So seriously, in fact, that he meticulously keeps track of how much time each project takes him-down to a hundredth of an hour! In addition to working on remodeling projects, Gary also works on cabinet projects for new homes. One particular project, on which he spent 10 hours creating a beautiful custom china cabinet, generated significant buzz in the builder community. Suddenly, everyone wants a cabinet just like that in their own new homes, even if it means it is no longer "unique." So, Gary has agreed to add that component to the rest of the homes in a particular development-eight in total. (a1) Gary realizes he saves time with each subsequent build when the design stays constant. Given Gary's historical learning curve of 70%, calculate the time needed for the second, fourth, and eighth cabinets. (Round answers to 2 decimal places, e.g. 15.25.)
