Your friend Amber has approached you seeking advice concerning two investment opportunities that she is presently considering. Her classmate Simone has asked her for a loan of $740 to help establish a small business; her neighbor Riley would like to borrow $545 as a personal loan. One year from now, Ambers original investment will be returned in either case, along with $67 of income from Simone or $70 of income from Riley. Amber can make only one investment.
