Find the selling price. explain how you solved the question. i might mark you as brainliest!

1) cost to store: 5o dollars
markup: 10 percent

2) cost to store: 80 dollars
markup 60 percent

3) cost to store 140$
markup: 25 percent

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 .

Omg that is a big question and weird words and i’m only 5
