The answer is B. I did the test and i got it right
So each individual bought one drink and one sandwich. The equation to find the cost is 21 = 3x + 6
Subtract 6 from both sides
15 = 3x
Divide 3 from both sides
x = 5
The price of each sandwich was $dollars.
Think of it, 5 + 5 + 5 = 15 (sandwiches)
15 + 2 + 2 + 2 = 21 (Drinks and the total sandwich amount)
Hope this makes sense, ask if you need more help! :)
F = P(1 + r)^t
F = future population
P = present population = 3000
r = growth rate per year as a decimal = 0.018
t = time in years = 8 (from 2007 to 2015, it's 8 years)
F = 3000(1 + 0.018)^8
F = 3460
The population will be 3460.

Answer:
The correct answer is (D)
Step-by-step explanation:
Given the events X and Y:
X = the price of stock X has increased
Y = the price of stock Y has increased
That means that the complement of these events are:
X' = the price of stock X has not increased
Y' = the price of stock Y has not increased
Hence, the event "the price of stock X has increased and the price of stock Y has not increased" may be written as:
X ∩ Y′
