Taylor is farsighted with a near point of 64 cm. What refractive power should be prescribed so that Taylor can read a book at a distance of 25.0 cm, in Diopter? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. (No unit is needed in your answer, it is already given in the question statement.)
