Question

You spend $22 to buy supplies for making necklaces and plan on selling them for $3 each. Find the minimum number of necklaces you have to sell in order to make a profit.

Let n represent the number of necklaces. in order to make a profit, you have to make more than $0, so u have inequality: 3n-22>0.
How many necklaces would you have to sell in order to make a profit?
_______ necklaces

Answer 1

8 necklaces

Explanation:

Solve for n in the inequality:

3n -22 > 0

Add 22 to both sides:

3n > 22

Divide each side by 3:

n > 7.33

We need to have full necklaces (whole numbers), so round this up to 8

So, you would have to see 8 necklaces to make a profit
