The original calculation, 5 × 3, represents the number of workdays Katie misses over 3 weeks (assuming 5 workdays per week). To express this as repeated addition, 5 × 3 means adding 5 three times: **5 + 5 + 5**.

- **Option A (3+5)** equals 8, not 15.
- **Option B (3+3+3)** equals 9, not 15.
- **Option C (5+5+5)** equals 15, matching 5 × 3.
- **Option D (5+5+5+5+5)** equals 25, which is incorrect.

The correct alternative expression is **C**.

5×3 means adding 5 three times, which is the same as 5+5+5.
C
minimax The question states that Katie is going on vacation for 3 weeks and she finds the number of days of work she will miss by multiplying 5 × 3. Multiplying 5 by 3 is equivalent to adding 5 to itself 3 times, which is the same as 5 + 5 + 5.

Therefore, the correct answer is:

C. 5+5+5

Explanation:
Katie is going to miss work for 3 weeks, and each week has 5 workdays (assuming a typical workweek of Monday through Friday). To find the total number of workdays she will miss, she can multiply the number of weeks by the number of workdays per week: 3 × 5 = 15.

Another way to find the total is by adding up the number of workdays she will miss each week. Since she will miss 5 days each week for 3 weeks, the expression that shows this is 5 + 5 + 5, which also equals 15.

Therefore, the correct answer is C.

Explanation: Katie is multiplying 5 days of work per week by 3 weeks to find the total number of days she will miss. Another way to represent this multiplication is by adding 5 three times, which is 5+5+5. This expression correctly represents the same total number of days. The other options do not correctly represent the multiplication of 5 days by 3 weeks.

Explanation: Katie multiplies 5 (the number of workdays in a week) by 3 (the number of weeks she will be on vacation) to find the total days of work she will miss. This is equivalent to adding 5 three times, which is represented by the expression 5 + 5 + 5.
