Answer:
k = 5
Step-by-step explanation:
Given that (x + 1) is a factor of f(x) then f(- 1) = 0
f(- 1) = 3(- 1)³ + 2(- 1) + k
= 3(- 1) - 2 + k
= - 3 - 2 + k
= - 5 + k
Then - 5 + k = 0 ( add 5 to both sides )
k = 5
P = -Q + 2518 = -Q + 2518-25 = -Q-7 = -Q-7/-1 = -Q/-1Q = 7
Therefore, the store can expect to sell 7 new books if they will charge $18 for the new books.
