Question

Anyone wanna help correct me?
A painting is purchased for $250. If the value of the painting doubles every 5 years, then its value is given by the function V(t) = 250 • 2t/5, where t is the number of years since it was purchased and V(t) is its value (in dollars) at that time. What is the value of the painting ten years after its purchase?
$1,000
$1,400
$1,800
$2,000
I did 250(2^5/5) and got 1600 but that's not an answer choice?

Answer 2
