Answer:
The profit/percent increase is $5.70
Explanation:
If you bought the umbrella for $6.00 and sold the umbrella for $11.70 there is a $5.70 profit/percent increase because if you want to calculate a profit, then you have to subtract the number you sold the item for by how much you spent on the item, so $11.70 - $6.00 is $5.70.
