The total amount is "x", so, if 22.8 is 58%, "x" is the 100%,
I wish I knew this one also
If you put them into to proportion
156/400 and then put a variable for the unknown x/1200
1200 divided by 400 = 3
156 times 3 = 468
468 order salad out of 1200
Hi there! The answer is x = 1


Rule AB = 0, gives A = 0 or B = 0

Therefore, the smallest of both roots is x = 1.
