Question

In 2005, a bottle of Pepsi cost $1.09 at the corner grocery store. In 2020, a bottle of Pepsi costs $1.19. What is the percent of increase of price (answer rounded to the nearest whole number)?

Answer 1

The percent of increase in the price of a bottle of Pepsi from 2005 to 2020 is approximately 9% when rounded to the nearest whole number.

Step-by-step explanation:

To calculate the percent of increase in the price of a bottle of Pepsi from 2005 to 2020, we need to follow a few steps.

Initially, we identify the initial price in 2005, which was $1.09, and the final price in 2020, which was $1.19. The difference in price can be found by subtracting the initial price from the final price.

The price increase is thus $1.19 - $1.09 = $0.10. To find the percentage increase, we divide the increase by the initial (2005) price and then multiply by 100 to convert it to a percentage. This gives us ($0.10 / $1.09) × 100, which is approximately 9.17%. Rounded to the nearest whole number, the percentage price increase is 9%.
