Final answer:
Albert's profit is $75 and his profit percentage is 27.27%.
Step-by-step explanation:
(a) Profit:
To calculate the profit, we subtract the cost price from the selling price. In this case, Albert's cost price was $275 and he sold it for $350. Therefore, his profit is $350 - $275 = $75.
(b) Percentage:
To calculate the profit percentage, divide the profit by the cost price and multiply by 100%. In this case, the profit is $75 and the cost price is $275. So, the profit percentage is (75 / 275) * 100% = 27.27%.
