Help!?!?!?!? 19. In a particular region of a national park, there are currently 330 deer, and the population is increasing at an annual rate of 11%. a. Write an exponential function to model the deer population. b. Explain what each value in the model represents. c. Predict the number of deer that will be in the region after five years. Show your work.

    Exponential Function \[y = ab^t\] a = initial population b = rate t = years y = population after t years

    y = 330(0.11)^5 Thats the equation i got when i plugged in the numbers. Now im solving it.

    It should be y = 330(1.11)^5

    The first way i solved it was by doing 1.11^5 and that equaled 1.6850581551. Then i multiplied it by 330 and got 556.069191183. Then i tried solving it a different way by multiplying 330 and 1.11 and got 366.3. Then i did 366.3^5 and got 6594541312769.34543. Now im assuming the first way i solved it is correct.

    There's ONLY one way to do it. It's called using order of ops.

    Yes, but you should always remember PEMDAS, especially since you are doing math on this level. Knowing PEMDAS should be second nature by now.
