((5-2)*180)/5=SPT
SPT=108
360-(108+90)=RPT
RPT=162
((n-2)*180)/n=162
162n=(n-2)*180
.9n=n-2
.1n=2
n=20
Juan’s lunch would have costed less if he paid separately. his lunch is 5.25

Answer:
D
Step-by-step explanation:
Exponential equation takes the form where
- a is the initial value ( a ≠ 0), and
- b is the base ( b ≠ 1)
The equation given in the problem can be written as , so it is <em>an exponential equation, </em> where a = -4.8 and b = 4.
Thus we can say that the initial value = -4.8 and the base is 4
The correct answer is D
