What is the annual growth rate of the paintings value? Write the answer as a percentage rounded to the nearest tenth

The function V=250(1.28)^d models the value of a rare painting, in thousands of dollars, d decades after is is sold at an auction for \$250,000. What exponential function modelss the value of painting after t years?

V=250(?)^t

V =250 (10^(t/93.27) )

or

V = 250 (1.02499^t)

$$\text{Ok, my response didn't really apply. I misunderstood what they wanted}\\ V = 250(1.28)^d\\ V = 250(1.28)^{\frac {t}{10}}\\ V = 250\left((1.28)^{\frac{1}{10}}\right)^t\\ V = 250(1.025)^t$$
