Question

Caitlyn sells necklaces to earn extra money. She charges $10 per necklace for material and $2.75 per hour to make unique gifts. How much would two necklaces cost together if one takes her an hour to make and the other three hours to make? Write an expression or equation and show your work and answer.

Answer 1

The price of one necklace is $10 plus $2.75 per hour.

If the first necklace took one hour to be made, its price is:

`\text{price}1=10+1\cdot2.75=10+2.75=12.75`

If the second necklace took three hours to make, its price is:

`\text{price}2=10+3\cdot2.75=10+8.25=18.25`

Now, calculating the total price, we have:

`\begin{gathered} \text{Total}=\text{price}1+\text{price}2=12.75+18.25 \\ \text{Total}=31 \end{gathered}`

So the total price of both necklaces together is $31.00
