Question

A charm bracelet costs $65, plus $25 for each charm. The equation −25x+y=65 represents the cost y of the bracelet, where x is the number of charms. How much does the bracelet cost? There are 13 charms.

Answer 1

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

Answer 2

I think it cost $390
