Answer:
$539
Step-by-step explanation:
First we need to look at the information given
Karen: $98.00
Emily: Karen x 3
Elizabeth: Emily /2
So if karen donated $98 and emily donated 3 times that all we need to do is multiply it by 3
$98*3= $294
So we now know that Emily donated $294
If Emily donated $294 and elizabeth donated half that all we need to do is divide $294 by 2
$294/2= $147
So we now know that Elizabeth donated $147
All we need to do know is add all three answers together $98+$294+$147=
$539
