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
