This type of problem is actually a trick problem. The question indicates that the PRODUCT of 3.93 and 0.07 would be about 4. The question is referring to the answer of the two values Multiplied to each other.
To visualize the question, we have:
3.93 x 0.07
This would give us:
0.2751
Kerri would be correct if she was looking for the SUM of the two values.
This would be:
3.93 + 0.07
This would give us:
4
Therefore in trick problems like this ones, it is better to look at what exactly is being asked.
No, Kerri is not correct because to visualize this question we have 3.93 times 0.07 and this would give us 0.2751. Kerri would be correct if she was looking for the sum of the two numbers.
This was similar to the other person who answered the question but I tried to make it more into a whole paragraph. Hope this helps :)
