A tablet is priced at $300. If the price increases by 10% and then decreases by 10%, what is the final price?

Step 1: Start with the original price of the tablet, which is $300.
Step 2: Calculate the amount of the 10% increase. This is done by multiplying the original price by 0.10: 0.10 * 300 = $30.
Step 3: Add the increase to the original price to find the new price after the increase: 300 + 30 = $330.
Step 4: Now, calculate the amount of the 10% decrease on the new price of $330. This is done by multiplying $330 by 0.10: 0.10 * 330 = $33.
Step 5: Subtract the decrease from the new price to find the final price: 330 - 33 = $297.
