<PRE><B>Question 1064108</B>
let x = the number of 15 kg bags.
let x + 2 = the number of 12 kg bags.


you have 12 * (x + 2) = 15 * x


simplify to get 12x + 24 = 15x


solve for x to get x = 8.


when x = 8, x + 2 = 10


15 * 8 = 120


12 * 10 = 120


8 bags of 15 kg each is equal to 10 bags of 12 kg each.


i believe, that&#39;s not just the least amount of flour the baker is buying, but it&#39;s the only amount of flour that the baker is buying, since the graphs of these two equations are straight lines and will only intersect at x = 8.
