To find the percent decrease in the price of the jacket from last week to this week, follow these steps:
1. Identify the prices:
- Last week's price: [tex]$159
- This week's price: $[/tex]130
2. Calculate the difference in price:
- Subtract this week's price from last week's price:
[tex]\[
\text{Difference in price} = 159 - 130 = 29
\][/tex]
3. Determine the percent decrease:
- Divide the difference in price by last week's price:
[tex]\[
\text{Percent decrease} = \left( \frac{\text{Difference in price}}{\text{Last week's price}} \right) \times 100
\][/tex]
- Plug in the values:
[tex]\[
\text{Percent decrease} = \left( \frac{29}{159} \right) \times 100 \approx 18.238993710691823
\][/tex]
4. Round to the nearest tenth of a percent:
- Round the calculated percent decrease to one decimal place:
[tex]\[
\text{Percent decrease (rounded)} \approx 18.2\%
\][/tex]
Thus, the percent decrease in the price of the jacket, rounded to the nearest tenth of a percent, is:
