The depletion of the Earth's ozone layer has created concern among some health experts. They believe that dramatic increases in the number of illnesses and deaths due to ultraviolet radiation rays may occur as a result of breaks in the ozone layer. The Environmental Protection Agency estimates about 22 times as many deaths due to skin cancer will occur in 2050 as occured in 2001.

Assuming that the annual number of skin cancer deaths increases arithmeticallly, about how many deaths might occur from skin cancer in 2020?
