Plz answer quickly. joseph bought some woodworking equipment. he paid $62 for a saw, $9 for a file set, and $4 for sandpaper.
what percent of the total cost of the equipment that joseph bought was the price of the file set? round to the nearest percent, if necessary.

The question asks to find what percent of the total cost was the price of the file set. Total cost was: $62 + $9 + $4 = $75. Now the total cost ( $75 ) represents 100% and the price of the file set ( $9 ) represents x %. When we make a proportion - 75 : 9 = 100 : x. 75 x = 9 * 100, 75 x = 900; x = 900 : 75; x = 12%. The file set was 12% of the total cost.
