Final answer:
Amanda will get $5 back in change.
Step-by-step explanation:
To find out how much money Amanda would get back in change, we need to subtract the cost of the skates from the amount she paid. Amanda paid with three $10 bills, so she paid a total of $30. The cost of the skates is $25. To find the change, we subtract $25 from $30:
$30 - $25 = $5
So, Amanda will get $5 back in change.
