The price of a cup of coffee was
$2.40
yesterday. Today, the price rose to
$2.55
. Find the percentage increase. Round your answer to the nearest tenth of a percent.
To find the percentage increase, we first need to calculate the amount of increase:
Amount of increase = New price - Old price
Amount of increase = $2.55 - $2.40
Amount of increase = $0.15
To find the percentage increase, we divide the amount of increase by the old price and multiply by 100:
Percentage increase = (Amount of increase / Old price) x 100
Percentage increase = ($0.15 / $2.40) x 100
Percentage increase = 6.25%
Therefore, the percentage increase is 6.25%. Rounded to the nearest tenth of a percent, it is 6.3%.
To find the percentage increase in price, we can use the following formula:
Percentage Increase = ((New Price - Old Price) / Old Price) * 100
Let's calculate it step-by-step using the given information:
Step 1: Find the difference in prices:
New Price - Old Price = $2.55 - $2.40 = $0.15
Step 2: Divide the difference by the old price:
$0.15 / $2.40 ≈ 0.0625
Step 3: Multiply the result by 100 to get the percentage:
0.0625 * 100 = 6.25
Step 4: Round the answer to the nearest tenth of a percent:
The percentage increase is approximately 6.3%.
Therefore, the percentage increase in price from $2.40 to $2.55 is approximately 6.3%.
