#=37#

#14=3/8(Total)#
or
#Total=(14)(8)/3#
or
#Total=37#

#37# bulbs

This is a direct proportion, showing a comparison between the number of dead bulbs and the total number of bulbs.

#3/8 = 14/x#

#3x = 8 xx14#

#x = (8xx14)/3#

=#37.33333#

The number of bulbs obviously cannot be a fraction so there are 37 or 38 bulbs.
