Answer:
The population after 15 years will be
Step-by-step explanation:
In this problem we have a exponential function of the form
where
a is the initial value
b is the base
r is the rate
b=(1+r)
x ----> the number of years
f(x) ----> the population
we have
The equation is
For x=15 years
substitute the value of x
therefore
The population after 15 years will be
Answer:
The price of an adult ticket is $7 and the price of a child ticket is $7
Step-by-step explanation:
Let
x -----> the price of an adult ticket
y ----> the price of a child ticket
we know that
<em>First day</em>
-----> equation A
<em>Second day</em>
----> equation B
Subtract equation B from equation A and solve for x
Find the value of y
substitute the value of x
therefore
The price of an adult ticket is $7 and the price of a child ticket is $7
30% = 30/100 = 3/10.
3/10 of 150000 is
45000. :)
