Question

Yvette is starting a jewelry business. She spends $120 on supplies and makes 18 necklaces. She wants to earn a profit equal to 3 times the amount she spent on supplies. Use this information to write 3 different equations Yvette could use to determine how much she should charge for each necklace.

Answer 1

Yvette wants to earn a profit of $360, then. That means she has to make a total of $480. 480 divided by 18 is 26 and 2/3. That basically rounds up to $26.67.

480 = 18x

360 = 18x - 120

120(3) = 18x - 120

(I'm not that good at this, so don't take my word for it)
