#7 Store A sells a watch for $50 and offers a 5% discount. Store B sells the same watch for $60 and offers a 20% discount.

From which store would you buy?

Notice that a 5%  discount is the same thing as selling something for  (100 - 5)% = 95% of its original price

 

So....the first watch costs   50  x . 95  =  $47.50

 

And...a 20% discount means the same thing as selling something for (100 - 20) %  = 80% of its original price

 

So.....the second watch  costs    60 x .80   =  $48

 

So...the first watch is the better deal
