The Cost of 1 DVD #=$12.4#

Explanation:

Cost of one DVD #=x#
Cost of 5 DVDs#=xxx5=5x#
Tax #=7%#

Tax for 5 DVDs #=5x xx7/100=(35x)/100#

Cost of 5 DVDs #(35x)/100+5x=(35x+500x)/100=(535x)/100#

Form an equation -

#(535x)/100=66.34#

Solve it for #x#

#x=66.34 xx 100/535=6634/535=$12.4#

The Cost of 1 DVD #=$12.4#
