Answer:
B. p
Step-by-step explanation:
Since, the simple interest is,
[tex]I=p\times r\times t[/tex]
Where, p is the invested or principal amount,
r is the annual rate of interest ( In decimal ),
t is the time ( In years ),
It is given,
$5,678 is invested at an annual interest rate of 4.5 percent for 6 years.
⇒ p = 5678, r = 4.5 % = 0.045 and t = 6,
Hence, he can substitute p for the value 5,678 in the simple interest formula.
