Suppose a culture of bacteria begins with 5000 cells and decreases by 15% each year. Write an equation that represents this situation.

• A = 5000(1 - 0.15)^t

• A = 5000(1 - 15)^t

• A = 5000(1 + 0.15)^t

• A = 5000(1 + 15)^t

The original value of a painting is $1400, and the value increases by 9% each year. Write an exponential growth function to model this situation.

• A = 1400(1 + 0.09)^t

• A = 1400(1 - 0.09)^t

• A = 1400(1 + 9)^t

• A = 1400(1 - 9)^t
