Five women bought dresses in a store for an average price of $96 each. A sixth woman bought a dress for $30 more than the average of all six. How much did she pay
I would appreciate answer with explaination.
Original sum : 5*96=480. Now the 6th's womens dress is x.
new avg: (480+x)/6=z we know x=z+30. now its (480+z+30)/6=6z. Just solve.
Now we want X so 102+30 = 132
