Oscar cuts grass for $20 a lawn. he is saving to purchase an mp3 player that costs $249.99. he will also have to pay 6% saless tax. how many lawns does he need to move to have enough money to buy the mp3 player ?

He would have to mow 14 lawns. To find the answer you would multiply 249.99 by 6%, then add the answer and round and you would get 264.99. 20 x 14 equals $280, so if he mowed 14 lawns and get $20 per lawn, he would buy the Mp3 and still have 15.01 leftover.

Hope this helps!
