Explanation:

Here's a real-world problem involving a percent increase with decimals:

Suppose you have a savings account with a balance of $500. The bank offers an interest rate of 2.5% per year. How much will your balance increase after one year, including the interest earned?

To solve this problem, we can use the formula for percent increase:

Percent increase = (new value - old value) / old value x 100%

Let x be the amount of interest earned after one year. Then, the new value of the savings account after one year is:

New value = old value + interest earned

New value = $500 + x

The percent increase is given as 2.5%, which can be written as a decimal as 0.025. Using the formula above, we can write:

0.025 = (New value - $500) / $500 x 100%

Simplifying this equation, we get:

New value - $500 = $500 x 0.025

New value - $500 = $12.50

New value = $512.50

Therefore, the balance of the savings account will increase by $12.50 after one year, which represents a 2.5% increase from the original balance of $500. The new balance will be $512.50.
