This equation is separable,

Integrate both sides and solve for
:




Solve for
using the initial value.

Then the particular solution is

Answer:
$133.56
Step-by-step explanation:
Multiply 180 and .3 and then subtract that number with 180
you should then get 126
multiply 126 by .06 you should get 7.56
Finally add 126 and 7.56 you should get your final price of 133.56
Solution:
As given , g(x)= f(x) + k --------(1)
As also given : f(x) =
(x+2)
g(x) =
(x+5)
Putting the value of f(x) and g(x) in equation (1).
→
(x+5) =
(x+2) + k
→
= k
→ k =
So , the value of k is 1.
