During a 5-year period, the amounts of merchandise (in millions of units) sold each year at stores A and B are modeled by the equations A = 13x + 8x - 3
and B =
8x^2- 3x + 11, where x = 1 represents the first year in the 5-year
period. Write a polynomial that represents the total amount of merchandise sold
cach years
