sorry so new to this site I get lost trying to see if anyone has answerd. My problem is : a group consisting of 2adults and 4children pay $76.00 entry to the zoo and a group consisting of 4adultd and 1child pay $82.00 . I need to solve my equations simultaneously to find out the admission cost for an adult and for a child I know it is probably really simple but so am I. kindest regards keljad
