Answer: 
Step-by-step explanation:
Let be "x" the original volume of the solution (in milliliters) before the acid was added and "y" the volume of the solution (in milliliters) after the addition of the acid.
Set up a system of equations:

Applying the Substitution Method, you can substitute the second equation into the first equation and then solve for "x":
Not sure what answer your needing so here is a breakdown of the amounts.
3 bracelets times $5 equals $15
How much is each necklace?
Subtract $15 from $40 you have $25 left. Then you divide $25 by 3 you get each necklace costs $8.33 so three necklaces cost $24.99
When you add $15 from the bracelets and $24.99 from the necklaces your total is $39.99 that’s why Megan gave the clerk $40
Hope this helps
