Answer 1

Wow !  Now THERE's an incentive !  I'm just glad I got in
early enough so that there's an answer block left open.

If you should happen to glance at these three problems,
you'll notice that they're all the same problem, just with
different numbers.  So if somebody showed you how to do
ONE of them, you'd know how to do ALL of them.

1).  Markup = 10% of $50 = 0.1 x $50 = $5
       Selling price = ($50 + $5)  =  $55 .

2).  Markup = 60% of $80 = 0.6 x $80 = $48
      Selling price = ($80 + $48)  =  $128 .
    
3).  Markup = 25% of $140 = 0.25 x $140 = $35
      Selling price = ($140 + $35)  =  $175 .

Answer 2

1) the fraction of 10/50 is convertable to a percantege easily. since 50 is 1/2 of 100, then you know to find 10 percent of 50 is simply to multiply 10 by 2 this gives you 20. add this to 50 and you get 70          2) first find 60 percent of 80. this is 48 add 48 to 80 and you get 128.           3) first find 25% of 140 you get 35. add 35 to 140 and you get 175
