Tracey paid $170 for an item that was originally priced at $580. what percent of the original price did tracey pay? round your answer to two decimal places.

29.31% 

Just divide the new price by the original price and multiply that by 100 :)

Ok do 170/580.
You get 0.2931
So round it to 0.29
Then that’s equal to 29%.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
