please please help...
martha bought a t-shirt, at $50 each, then she bought a hat for $70 and a pair of shoes for $180. She also bought a skirt, but she does not
remember the price.
If the average price per item was $120, find the price of the skirt.
The price of the skirt was $...?

($50+$70+$180+price of skirt)/4 =average price=$120
hence $50+$70+$180+x=$120*4=$480
hence x=$480-($50+70+180)=$360
hence price of skirt is 360
rbf166:
$480-($50+70+180)=$180 not 360?
can you check again?
$480-$300=$180
please write it down and do the calculations on a paper if your doubt persists
