Apainting is purchased for $450. if the value of the painting doubles every 5 years, then its value is given by the function v(t) = 450 • 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'm terrible at word problems, so if someone can give me step-by-step , that would be amazing.
