The answer is B. Kristine is exactly 9 inches taller than Colleen
Divide $14,000 by $9.99 = 1401 board games
Since we know $14,00 is how much has been spent on the board game in total, the price to make each board ($1.90) game isn't necessarily relevant.
So you take the profit made from each game and divide that from how much was spent for the board game.
26 green apples
if you do 0.4 * 65 you get <u>26</u> which is 40% of 65

Answer:
v(b) = 4,5 mil/h speed of the barge in still water
Step-by-step explanation:
d = v*t barge going upstream 12 miles and 4 hours trip
barge returning back 12 miles and 2 hours trip
let call v(b) barge velocity and
v(w) water velocity
d = 12 (Mil) = 4 (h)* [(v(b) - v(w)]
3 = v(b) - v(w) (1)
d = 12 (mil) = 2 (h) * [ (v(b) + v(w)]
6 = v(b) + v(w) (2)
Equations (1) and (2) is a two system equation. Solving
from equation (1) v(w) = v(b) - 3
By subtitution in equation (2)
6 = v(b) + v(b) - 3
9 = 2v(b)
v(b) = 9/2 ⇒ v(b) = 4,5 mil/h
