Answer:
44 ounces
Step-by-step explanation:
Begin by setting up your equation in the following format:
(Percent)(Amount) + (Percent)(Amount) = (Percent)(Amount + Amount)
In this case, your equation should look like this:
(0.15)(x) + (0.20)(11) = (0.16)(x + 11)
where x stands for the number of ounces of the 15% alcohol solution needed.
Next, we can begin simplifying to solve for x. Your work should look similar to this:
(0.15)(x) + (0.20)(11) = (0.16)(x + 11)
0.15x + 2.2 = (0.16)(x + 11)
~ Multiply both sides by 100 to eliminate all of the decimals ~
15x + 220 = 16(x + 11)
15x + 220 = 16x + 176
15x = 16x - 44
-x = -44
x = 44
This means that 44 ounces of 15% solution must be mixed with 20% solution to make 16% solution
~Hope this Helps!~
Answer:
4
Step-by-step explanation:
256 = x^4
Take the 4th root of both sides.
4^√256 = 4^√x^4
<u>4 = x</u>
Answer:
Step-by-step explanation:
A 36% discount means the selling price is (100-36)% = 64% of the original price.
$272 = 64% of x = 0.64·x
x = $272/0.64 = $425
