2nd 6 month = 20% down of first 6 month
= 20% down of 324
= 80% of 324
= <u>259.20</u>
3(3-y)+1=31
9-3y+1=31
10-3y=31
-3y=31-10
-3y=21
y=-21/3 = -7
the solution is y=-7

Answer:
b ≈ 101.52
Step-by-step explanation:
Given two sides and the angle between, the Law of Cosines is useful.
b^2 = a^2 +c^2 -2ac·cos(B)
b^2 = 105^2 +9^2 -2·105·9·cos(65°) ≈ 10307.251
b ≈ √10307.251
b ≈ 101.52
