Answer:
screw this question
Step-by-step explanation:
To change from 15% to 25% he needs to add 10%.
If the solution is 50ml then he needs to add 10% which is 5ml... But if he adds 5 ml then the solution will be 55ml total, so that doesn't make sense. He has to take some of the solution that's not acid before adding the 5ml...
The x coordinate is halfway between 2 and 10 = 2 + (10-2)/2 = 2+4 = 6
so midpoint is C (6,3)
<u>Find amount spent on magazines:</u>

<u>Find number of books:</u>
Number of books = $35.80 ÷ $8.95 = 4
