What i did is that i did $1.50 time 8 = $12.00 and then do $30.00-12.00=$18.00
7a + 6c + 9a - 15c
-- Look for all the 'a's 7a, 9a
-- Addum up 16a
-- Look for all the 'c's 6c, -15c
-- Addum up -9c
-- Write the results 16a - 9c
Answer:
15.035 years
Step-by-step explanation:
The exponential function to calculate population growth is
P(t) = Poe^kt
P(t) = Population size after t years = 3.6 million
Po = Initial population size = 2.1 million
k = growth rate = 3.65% = 0.0365
t = time in years = ???
Hence:
3600000 = 2100000 × e ^0.0365t
Divide both sides by 2100000
3600000/2100000 = e^0.0365t
1.7142857143 = e^0.0365t
Find the log of both sides
Log 1.7142857143 = log (e^0.0365t)
Log 1.7142857143 /Log 0.0365 = t
t = 15.035 years
