How much does James get for the first lesson? ** The first lesson is free.
How much do the first 10 lessons cost? ** The lessons 2 to 11 cost 10*$5=$<<10*5=50>>50.
How many remaining lessons does James have? ** He then had 9 remaining lessons where he had to pay for every other one.
How many lessons does James pay for? ** So he pays for lessons 13,15,17&19 = 4 lessons.
How much do the remaining lessons cost? ** Those lessons cost 4*$5=$<<4*5=20>>20.
How much did James pay in total? ** So in total, the cost was $50+$20=$<<50+20=70>>70.
How much did James pay? ** So he paid $70/2=$<<70/2=35>>35.
