Answer: y=390

Step-by-step explanation:

To find the solution first you have to isolate y (the cost of the bracelet) in the equation:

-25x+y=65\\y=65+25x

Then, you substitute the given value of x (number of charms) into the equation:

y=65+25(13)

And you solve:

y=65+325\\y=390\\

Therefore, the bracelet costs $390
