Final answer:
To find the increase in price from $300 to $357, you subtract the original price from the new price, resulting in an increase of $57.
Step-by-step explanation:
To find the increase in price from $300 to $357, you calculate the difference between the two prices. This can be done by subtracting the original price ($300) from the new price ($357).
Step 1: Write down the new price and the original price.
New price = $357
Original price = $300
Step 2: Subtract the original price from the new price.
Increase in price = New price - Original price
Increase in price = $357 - $300
Step 3: Calculate the result to find the increase.
Increase in price = $57
Therefore, the increase in price is $57.
