Please help me. Abby, Julia, Kim, and Jeanie had collected donations following a walkathon. Abby had collected 3 times as much as Julia. Kim had collected $25 less than Abby. Jeanie had collected twice as much as Abby. Then Jeanie received a check from her grandmother for $55, which gave her the same combined total amount that Abby, Julia, and Kim had collected. Find the amount that Julia collected.

Respuesta :

From the above information, if we assume Julia collected x, then Abby will be 3x (three times as Julia) while Kim will be (3x-$25) ($25 less than Abby) and Jeanie will be 6x (twice as Abby).
The total for Julia, Kim and Abby was $ 55. Therefore, x + (2x -$25)+ 3x =55
   6x -25 =55
        6x = 80
          x = 13.3
 Hence, Jeanie collected $ 80 (6 x)
