How much money does Vincent earn for selling 5 fantasy books per day? ** Vincent earns $4 x 5= $<<4*5=20>>20 for selling 5 fantasy books per day.
How much does a literature book cost? ** The price of the literature book is $4/2 = $<<4/2=2>>2 each.
How much money does Vincent earn for selling 8 literature books per day? ** He earns $2 x 8= $<<2*8=16>>16 per day for selling 8 literature books.
How much money does Vincent earn per day? ** So the total money he earns per day is $16 + $20= $<<16+20=36>>36.
How much money will he earn after 5 days? ** Therefore, he will earn $36 x 5= $<<36*5=180>>180 after 5 days.
