Algebra

A biologist studied the populations of black bear and brown bears over a 10-year period. The biologist modeled the populations, in thousands, with the following polynomials where x is time, in years.

black bears: 2.3x^2 - 5.6x + 2.3
brown bears: 2.4x^2 + 7.2x + 0.97

What polynomial models the total number of brown and black bears?

a) 4.7x^2 + 1.6x + 3.27
b) 4.7x^2 - 1.6x - 3.37
c) 4.7x^2 + 1.6x - 3.37 <---- My Answer
d) 4.7x^2 - 1.6x + 3.37
