Answer 2

24 calories

Explanation:

According to the given, sugar-free gum has 40% less calories than regular gum. We can take this to mean that sugar free gum has 60% of the calories of regular gum.

To find out the answer to the problem, all we have to do is multiply the number of calories of regular gum by 60% or 0.60.

`(60%)(40` calories`)`
`=0.60(40` calories`)`
`color(red)(=24)` calories
