14. A large piece of aluminum is gradually pressed into a thin sheet by passing through rollers. Each pass through the rollers results in a thinner piece of aluminum according to the equation A= 80 (0.75), where A represents the thickness of the aluminum (in millimetres), and x represents the number of passes through the rollers. How many passes are needed to end up with a 1.5 mm thick sheet of aluminum?
