Step-by-step explanation:
The amount spent on soap = $12
The spent on sponges and rags = $19
So, the total amount spent by cheerleader Â
= Amount spent on (Soap + Buckets/ Sponges) Â = $12 + $19 = $31
So, they total spent  is $31 before car washing.
Now, the amount they earned from car washing  = $25
Here, as we can say: Â
$31 Â > $25
⇒ The amount spent  is more than  the amount earned.
So, there is loss in the given activity.
Loss = Amount spent - Amount earned Â
    = $31 - $25 = $6
So, the integer expression $6 shows their loss.
This represents that they spent $6 more than the amount they actually earned.
