Use the table to determine if the change is linear or exponential. Identify and interpret the constant rate of change if it's linear or the common ratio if it's exponential. It may not have an exact common ratio. In this case, approximate the ratio.
A local golf tournament begins with 200 participants. After each round, players are eliminated according to the table below.

O A. The change is linear. The constant rate of change is -50
OB. The change is exponential. The common ratio is about 0.75
OC. The change is exponential. The common ratio is about 1.25.
OD. The change is linear. The constant rate of change is 50
Interpretation:
O A. The number of players increases about 50 players each round,
OB. The number of players decreases about 50 players each round.
OC. The number of players decreases about 25% each round.
OD. The number of players decreases about 75% each round.
