We can write a system of equations with the information given.

We know that the total amount of jewelry sold is 37. We can also express the total amount of jewelry sold as the sum of the number of bracelets B sold and the numebr of necklaces N sold. Then, we can write the first equation as:


B+N=37

The total amount of money is $97. This is the sum of the bracelet sales and the necklaces sales. We can express each sale as the product of price and the quantity.

For example, the bracelets sales are equal to 2*B, as 2 is the unit price and B is the amount of bracelets sold.

Then, we can write:


2\cdot B+3\cdot N=95

Now, we have a system of equations with 2 equations and 2 unknowns.

We can solve it by substitution as:


B+N=37\longrightarrow B=37-N
\begin{gathered} 2B+3N=95 \\ 2(37-N)+3N=95 \\ 74-2N+3N=95 \\ N=95-74 \\ N=21 \end{gathered}
B=37-N=37-21=16

Answer: you sold 16 bracelets and 21 necklaces.
