This exploration investigates whether an employee would be better off with a salary of 20 dollars a day for a week or with a salary that starts at 2 dollars a day and doubles every day. The exploration, part of the Figure This! collection of 80 math challenges, extends the salary question to examine other number patterns with different rates of change. The challenge page contains links to a solution hint, the solution, and other questions such as how much will a person earn in one month based on each salary scheme. The Did You Know area describes and illustrates the difference between geometric and arithmetic sequences. How bank interest is calculated is also discussed.
