Jenna is making necklaces (n) and bracelets (b) to sell at a craft fair. The price of each necklace is $12 and the price of each bracelet is $7. Jenna has enough beads and wire to make no more than 30 pieces of jewelry. She would like to make at least $240 at the fair. Which system of inequalities models this situation?

12n+7b ≥240

n+b ≤ 30

Step-by-step explanation:

Hi, to answer this question we have to write 2 equations:

First one:

The number of necklaces (n) plus the number of bracelets (b) must be less or equal to the amount of pieces of jewelry that she can make (30).

n+b ≤ 30

Second one:

The product of the number of necklaces (n) and the price per necklace (12) ; plus The product of the number of bracelets (b) and the price per bracelet (7) ; must be greater or equal to the amount of money that she wants to make (240).

12n+7b ≥240

The system of equations is:

12n+7b ≥240

n+b ≤ 30

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
