Write an explicit rule which can be used to determine the value of her art collection n years after that. Use this to determine the value of her collection 10 years after she started tracking its worth rounded to the nearest dollar.
Answer:
Value = 500000 × (1.1^n)
$1,296,871
Step-by-step explanation:
a = 500000
r = 550000 ÷ 500000 = 1.1
1st term is the initial year:
n years after that is the "n+1"th term
Value = 500000 × (1.1^n)
n = 10
500000(1.1¹⁰)
1,296,871.23005
