Bert has a garden shop. He buys his products in a warehouse and sells them for $10 more in his shop. From each sale, he has to pay 10% of the value in tax. One day a client came to his shop and bought a barrel for $90. How Much money did Bert make on this sale?
Thoughts? Step-by-step reasoning:
First, we need to know how much Bert paid for the barrel in the warehouse, and that is 90 - 10 = $80. The tax from the sale stands at 10 / 100 * 90 = $9. That means Bert earned 90 - 9 - 80 = $1 on the sale.
Thus, the answer is 1.
