The answer is 1 by multiplying by itself
Account B will cost less because
Account A will cost 0.2*20= $4
Account B will cost
0.1*20 +1.5= 2+1.5= $3.5
First, you need to find how much an ounce costs. To do that, you have to divide 1.39 by 8. Then you get about 0.17. Now, you multiply 0.17 by 14, and get the answer of 2.38. Therefore, a 14-oz bottle of ketchup costs $2.38.
2/3x + 7 = x-7
+7 +7
---------------------
2/3x + 14 = x
-2/3x -2/3x
----------------------
14 = 1/3x
*3 *3
-------------
42 = x
Hope this helps! :)
