**Text Transcription:**

11. Monday morning started out at -3 degrees in Minneapolis, Minnesota. By Monday afternoon, the temperature was 18 degrees above zero. What is the difference in temperatures on this day?

12. Shumina started with $65 in her bank account. After going on a spending spree, she realized her balance was now at $10. What is the difference in her bank account from where she started to where she ended?

13. Which has the greater absolute value and why?
|-99| or |55|

14. Write 2.3 x 10^-6 in regular notation.

15. Order the following from least to greatest: 5.5 x 10^3, 8.9 x 10^3, 5.4 x 10^7

---

**Detailed Explanation:**

- **Question 11:**
  This question involves calculating the difference between two temperatures to determine how much the temperature rose from morning to afternoon. The starting temperature is -3 degrees, and the afternoon temperature is 18 degrees. To find the difference, subtract -3 from 18, resulting in a total temperature change of 21 degrees.

- **Question 12:**
  This problem asks for the change in Shumina's bank account balance. She started with $65, and her final balance is $10. Subtracting the final amount from the initial amount gives a difference of $55, indicating Shumina spent $55.

- **Question 13:**
  This question requires understanding of absolute values. The absolute value of a number is its distance from zero on the number line, regardless of direction. Here, |-99| has an absolute value of 99, while |55| has an absolute value of 55. Thus, |-99| has the greater absolute value.

- **Question 14:**
  In scientific notation, 2.3 x 10^-6 is converted to regular notation by moving the decimal point six places to the left. Therefore, the answer is 0.0000023.

- **Question 15:**
  This task involves ordering numbers in scientific notation. Convert these to regular numbers for easy comparison: 
  - 5.5 x 10^3 = 5500
  - 8.9 x 10^3 = 8900
  - 5.4 x
