Question 4

You are asked to design a new set of coins. All coins will be circular and colored silver, but of different diameters 
   
Researchers have found that an ideal coin system meets the following requirements: 
Diameters of coins should not be smaller than 15 mm and not be larger than 45 mm. 
Given a coin, the diameter of the next coin must be at least 30% larger. 
The minting machinery can only produce coins with diameters of a whole number of millimeters (e.g., 17 mm is allowed, but 17.3 mm is not.). You are asked to design a set of coins that satisfy the above requirements. You should start with a 15-mm coin, and your set should contain as any coins as possible. What would be the diameters of the coins in your set?

Accepted Answer

The answer of You are asked to design a new...
