Okay so we have $\large 85 \le 15c + 85 \le 250$

85 because this is the fixed cost of the bracelet with no charms
15c because this is the cost of each charm

and they save anywhere between 85 and 250   so this would shade all the amounts of charms they can buy

Quite frankly I would just do a number line...

We need to simplify that a bit more...

$$\large 85 \le 15c + 85 \le 250$$
$$\large 0 \le 15c \le 165$$
$$\large 0 \le c \le 11$$

This shows that you can buy anywhere from 0 to 11 charms for this bracelet..
