During the period 1998-2002, the number a (in millions) of books for adults and the number k (in millions) of books for kids sold can be modeled by
a = 9.5t³ - 58t² + 66t + 500 and k = -15t² + 64t + 360
where t is the number of years since 1998.
write and equation that gives the total number (in millions) of books for adults and kids sold as a function of the number of years since 1998.
hint: add the two polynomials together.
