A farsighted woman breaks her current eyeglasses and is using an old pair whose refractive power is 1.750 diopters. Since these eyeglasses do not completely correct her vision, she must hold a newspaper 42.00 cm from her eyes in order to read it. She wears the eyeglasses 2.00 cm from her eyes. How far is her near point from her eyes?
