Answer:
Simplifying
an = 8n + -7
Reorder the terms:
an = -7 + 8n
Solving
an = -7 + 8n
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Divide each side by 'n'.
a = -7n-1 + 8
Simplifying
a = -7n-1 + 8
Reorder the terms:
a = 8 + -7n-1
Answer:
614.25
Step-by-step explanation:
The amount of interest is computed using ...
... I = Prt . . . . . where P is the principal amount, r is the annual interest rate, and t is the number of years.
Here, the interest is ...
... I = 520×0.075×(2 5/12) = 39×29/12 = 94.25
The total amount due, interest plus principal, is ...
... 94.25 + 520 = 614.25
