On January 1, 2010, an investment was worth $1000. By the end of 2010 the investment had lost 30%. What percent must the investment grow by in 2011 to be worth $1000 by the end of 2011? Round your answer to the nearest tenth of a percent.
percent=1000/700= 143 percent, so the increase is 43 percent
