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.

Step-by-step explanation:

Given : 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).

Then , the cost of N necklaces = $8N

Cost of B bracelets = $7B

Total money spent =  Cost of N necklaces+ Cost of B bracelets

=$(8N+7B)

She spends less than $120.

i.e. $(8N+7B) < $120

Hence, the inequality models this situation :

this doesn't make sense lol

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
