disa [49]
Below are the choices:

A. 80 mL of the 3.5% solution and 120 mL of the 6% solution 

<span>B. 120 mL of the 3.5% solution and 80 mL of the 6% solution </span>

<span>C. 140 mL of the 3.5% solution and 60 mL of the 6% solution </span>

<span>D. 120 mL of the 3.5% solution and 80 mL of the 6% solution
</span>
Let fraction of 3.5% in final solution be p. 

<span>p * 3.5 + (1 - p) * 6 = 4.5 </span>

<span>3.5p + 6 - 6p = 4.5 </span>

<span>2.5p = 1.5 </span>

<span>p = 3/5 </span>

<span>3/5 * 200 = 120 </span>

<span>Therefore the answer is B. 120 ml of 3.5% and 80 ml of 6%.</span>

Perform the operation(s) and write the answer in simplest form.
ss7ja [257]
First do 12-5, which equals 7.  Next, subtract 1/10 from 2/5.  2/5 is the same as 4/10 if you multiply both the numerator and denominator by 2.  4/10-1/10=3/10. Now add 7 and 3/10.  You will get 7 3/10 as the answer, which is letter C.)
