For this case we have the following equation:
It is a second degree equation of the form:
Where:
The discriminant is given by:
Since it is greater than zero, then there are two different real solutions.
Option C
Ответ:
$289.66
Step-by-step explanation:
A=P(1+r)^t
P=250
r= .0375
t= 4
A=250(1+.0375)^4
A= 289.66
