Answer:

Step-by-step explanation:

DE :
If y is a solution of given DE then it satisfied the DE.
Differentiate w.r.t t

Using the formula

LHS:
RHS

By using the formula

LHS=RHs
Hence, y is a solution of given DE

$33,075 = 0.05S + S
$33,075 = 1.05S
$33,075/1.05 = 1.05S/1.05
S= $31,500
Check
$31,500 * 5% = $1575 + $31,500 =$33,075
The equation of the blue graph is A.
