Question

**Title: Calculating Percent Increase in Tire Pressure**

**Instructions:**
When finding the percent, round to the nearest tenth of a percent when necessary.

---

**Understanding the Problem:**
To find the percent increase, use the formula for percent change:

\[
\text{Percent Increase} = \left(\frac{\text{New Value} - \text{Original Value}}{\text{Original Value}}\right) \times 100
\]

**Steps to Solve:**
1. Identify the original and new values of the tire pressure.
2. Subtract the original value from the new value.
3. Divide the difference by the original value.
4. Multiply the result by 100 to get the percentage.
5. Round to the nearest tenth.

**Example Calculation:**
Original Pressure = 32 psi
New Pressure = 37 psi

Calculate the difference:
\[ 37 - 32 = 5 \]

Calculate the percent increase:
\[ \left(\frac{5}{32}\right) \times 100 = 15.625\% \]

Round to the nearest tenth:
\[ 15.6\% \]

**Final Answer:**
The percent increase in pressure is 15.6%.

Use this method whenever you need to determine the percentage increase or decrease in a value, ensuring to round properly as instructed.
