Alice buys some inexpensive bracelets and necklaces as party favors for her jewelry showing. she pays $8 for each necklace (n) and $7 for each bracelet (b). she spends less than $120. which inequality models this situation?
a) 7b + 8n ≤ 120
b) 7b + 8n > 120
c) 7b + 8n ≥ 120
d) 7b + 8n < 120

D) 7B + 8N < 120

Step-by-step explanation:

Given,

The cost of each necklace = $ 8,

So, the cost of N necklace = 8N dollars

Also, the cost of each bracelet = $ 7,

So, the cost of B bracelet = 7B dollars,

Thus, the total spending = 7B + 8N,

According to the question,

Total spending is less than $ 120,

⇒ 7B + 8N < 120

Hence, OPTION D is correct.
