The directions are Find a formula for the inverse of the function described below. An organization determines that the cost per person of chartering a bus is given by the formula C(x)=250+4x/x where x is the number of people in the group and C(x)is in dollars.So find the inverse of the function C(x)=250+4x/x. </SPAN>\n" );
