# A concert ticket that originally cost $18.50 is on sale for $14.00. What is the percent of decrease, rounded to the nearest tenth?

24.3%

The decrease in cost = $18.50 -$14.00 = $4.50

We write this down to represent the percentage decrease.

The first digit following the decimal point, or 3, is the tenths value.

We must take into account the digit that comes right after, or the hundredths, in order to round this.

3 'rounds up' to 4 if the value is less than or equal to 5.

• The 3 remains at 3 if the value is less than 5.

Since the digit in the hundredths column has a value of 2, 3 remains.

Hence, 24.3% (to the nearest tenth) is the percentage decrease.

To find the percent decrease:

Percent Decrease = ((Original Price - Sale Price) / Original Price) * 100%

Percent Decrease = ((18.50 - 14.00) / 18.50) * 100%

Percent Decrease ≈ (4.50 / 18.50) * 100%

Percent Decrease ≈ 0.2432 * 100%

Percent Decrease ≈ 24.32%

Rounded to the nearest tenth, the percent decrease is approximately 24.3%.
