Question

The temperature in an oven changes from 350° to 362°. What is the percent increase in temperature, to the nearest tenth of a percent?

A) 2.9%
B) 3.1%
C) 3.4%
D) 4.0%

Answer 1

To find the percent increase in temperature, subtract the initial temperature from the final temperature and divide by the initial temperature. The percent increase is approximately 3.4%.

Step-by-step explanation:

To find the percent increase in temperature, we need to calculate the difference between the final temperature and the initial temperature, and then divide that difference by the initial temperature.

Step 1: Initial Temperature = 350°F

Step 2: Final Temperature = 362°F

Step 3: Difference = Final Temperature - Initial Temperature = 362°F - 350°F = 12°F

Step 4: Percent Increase = (Difference / Initial Temperature) * 100%

Substituting the values: Percent Increase = (12°F / 350°F) * 100% ≈ 3.4%

Therefore, the correct answer is C) 3.4%.
