Which of the following is equivalent to the sum of 3x4 +2x3 and 4x4 +7x3 ?
- 16x4
- 7x8 +9x6
- 12x4 +14x3
- 7x4 +9x3
The correct answer is: 7x4 +9x3
(3x4 + 2x3) + (4x4 + 7x3)
= 3x4 + 4x4 + 2x3 + 2x3
= 7x4 + 9x3

There were no jackrabbits in Australia before 1788 when 24 jackrabbits were introduced. By 1920 the population of jackrabbits had reached 10 billion. If the population had grown exponentially, this would correspond to a 16.2% increase, on average, in the population each year. Which of the following functions best models the population p(t) of jackrabbits t years after 1788?
