A lens maker is creating eyeglasses for a farsighted patient, whose near point is 100 cm. The lens maker is using a mold that fixes the front radius of curvature of the lens to be 2 cm. If the index of refraction of the lens is 1.5 and patient's desired near point is 15 cm, to what radius of curvature in centimeters must the lens maker must grind the back surface of the lens?

A lens maker is creating eyeglasses for a farsighted patient, whose near point is 100 cm.
The lens maker is using a mold that fixes the front radius of curvature of the lens to
be 2 cm. If the index of refraction of the lens is 1.5 and patient's desired near point is
15 cm, to what radius of curvature in centimeters must the lens maker must grind the back surface of the
lens?
