The answer is 1. f(a) = –2a^2 – 5a + 4. If a = -3, then to find f(-3) we
have to substitute a in the general formula. f(a) = –2a^2 – 5a + 4 = -2
* a^2 – 5 * a + 4. Substitute a with -3. f(-3) = –2 * (-3)^2 – 5 * (-3)
+ 4 = -2 * 9 - (-15) + 4 = -18 + 15 + 4 = 1

They need to replace 1972 chairs. First you have to multiply 5 x 136. That would equal 680. Then it says a sixth section contains 348. So you would add 680 + 348. That would equal 1028. Then subtract, 3000 - 1028 = 19272.
Hope this helps.
