5×500=2,500
5 × 500 = 2 , 500

5×600=3,000
5 × 600 = 3 , 000

7×600=4,200
7 × 600 = 4 , 200

7×500=3,500
7 × 500 = 3 , 500

Answer 1

To determine which estimate shows that Frank's answer of 3,696 is reasonable, we can look for an estimate that is close to this value.

Let's evaluate the estimates given:

1. **5 × 500 = 2,500** (This is far from Frank's answer)
2. **5 × 600 = 3,000** (This is still quite low compared to 3,696)
3. **7 × 600 = 4,200** (This is higher than 3,696, but not too far off)
4. **7 × 500 = 3,500** (This estimate is very close to 3,696)

Among these estimates, **7 × 500 = 3,500** is the closest to Frank's result of 3,696, making it a reasonable estimate.

So, the correct response is:
**7 × 500 = 3,500**.
