Answer:
25n + 18b ≤ 500.
Step-by-step explanation:
Let, the number of necklace = n and the number of bracelets = b.
It is given that the Hannah uses 25 beads per necklace and 18 beads per bracelet.
So, the number of beads per 'n' necklaces is [tex]25n[/tex] and the number of beads per 'b' bracelets is [tex]18b[/tex].
Since, the maximum number of beads can be 500.
We get the inequality,
25n + 18b ≤ 500.
