If the COST of each fan (presumably including a share of overhead, etc.) is X then you are a saying that 95% of
X is 475: .95X= 475. In order to gain 5% he must sell for 105% of cost 1.05X. Since X= 475/.95, that is
1.05X= 1.05(475/.95). Do that arithmetic.
Another way to do this is to argue that if 475 is 95% of the cost, then because 95= 5(19) 5% is 475/19. And since "1.05%" is 95% plus 2 times 5%, we must add 2 times 475/19 to 475. 475+ 2(475/19)= 475(1+ 2/19)= 475(21/19)
