<span>|3x| = 12 actually represents two equations: 3x = 12 and -3x = 12.
Thus, the solutions are {-4, 4).</span>
Whatever% of anything is just (whatever/100) * anything.
x = ounces of 14% iodine.
y = ounces of 29% iodine.
we know that in a 14% iodine solution, 14% is iodine and the rest is something else, we also know that "x" ounces of the solution have 14% of iodine, how much is that? (14/100) * x, or 0.14x.
likewise, in the 89 ounces of 47% solution there is (47/100) * 89 of iodine.
and likewise as well, in "y" ounces of 29% iodine there is (29/100) * y, or 0.29y of iodine.
bearing in mind that, whatever "x" and "y" may be, x + 89 = y, and that the sum of the iodine amounts also will equate 0.29y.
Answer:
$147.01
Step-by-step explanation:
$58.64 - $32.50 is $26.14
$26.14 + 46.25 is $72.39
$72.39 - ($16.04+$7.50) is $48.85
Lastly, 48.85 + $98.16 = $147.01
