Answer :
<u>Given</u><u> </u><u>-</u>
- Books read by aya = 5
- Total number of books read by them = 14
<u>To</u><u> </u><u>find</u><u> </u><u>-</u>
- How many books does luka reads.
<u>Solution</u><u> </u><u>-</u>
Here, total number of books is 14 and books read ny aya is 5 . To find the luka reads We'll subtract total number of books read by them from books read by aya.
→ 14 - 5
→ 9
<u>There</u><u>fore</u><u>,</u><u> </u><u>9</u><u> </u><u>books</u><u> </u><u>read</u><u> </u><u>by</u><u> </u><u>luka</u><u>.</u><u> </u>
X + y = 20 --> eqn 1
The second equation would be the mass balance shown below:
(x)(0.40) + y(0.70) = 20(0.52) --> eqn 2
Rearranging eqn 1,x = 20 - ySubstitute this to eqn 2:
(20 - y)(0.40) + y(0.70) = 20(0.52)Solve for y,y = 8 grams Finally, solve for x.x = 20 - 8 = 12 grams
Therefore, Serena needs 12 grams of the 40% solution and 8 grams of the 70% solution.
