Answer:
15
Step-by-step explanation:
We can round the two numbers so then we can multiply by the rounded numbers to get a close answer.
4.9 rounded to the nearest whole number is 5.
3.1 rounded to the nearest whole number is 3.
Now, we can multiply by the two numbers we got here.
5 × 3 = 15, so the answer to the question is 15.
