5 cans need to be bought. There are three servings in each can so you divide 15 by 3.
<span> 3x - 6
3(x-2)-6
3x-6-6
3x-12< your answer </span>
1.4•1.58= 2.212 is your answer because if it cost 1.58 per pound and it is 1.4 lbs your answer will be 2.212
3 3/4 inches = (3 3/4 / 12) feet = 0.3125 feet
120 feet requires ------- x number of board.
120 feet/0.3125 feet / board = 384 boards.
1 board costs 1.40
384 boards cost x
1.4 * 384.00= x*1 = x
537.60 dollars.
Note if you need to do this by dimensional analysis, it will look like this.
120 feet/fence [ 1 board / 3.75 inches] [ 12 inches/foot] [1.40 dollars / board]
All units that can be cancelled should be.
The result is 537.6 dollars / fence which is the answer you got.
