Answer: $9.00
Explanation:
If Dave wants to buy a table saw that is worth $291, and he pays with $300 cash, he will receive $9 in change.
To calculate this, you can subtract the cost of the table saw from the amount of cash Dave is paying:
$300 (cash) - $291 (cost of table saw) = $9 (change)
$9 is the amount of money that the seller will have to return to Dave as the balance after purchasing the item.
