What is the total sum if you add $30, $50, and $20 together?

$90
$100
$80
$70

The correct answer is: $90

To find the total sum of $30, $50, and $20, you simply need to add these amounts together. Start by adding the first two amounts: $30 + $50 equals $80. Next, add the remaining amount to that sum: $80 + $20 equals $100. Therefore, the total sum of $30, $50, and $20 is $100. This value of $100 reflects the accurate addition of all three amounts. The other options provided do not represent the correct total when all amounts are accounted for in a straightforward addition process.
