Final answer:
The jeweler made a system of equations to determine the number of bracelets and necklaces made.
Step-by-step explanation:
We can define two variables to represent the number of bracelets and necklaces made:
Let B = number of bracelets
Let N = number of necklaces
Then we can write the following system of equations:
Equation 1: 5B + 16N = 130 (the total amount of gold used is 130 grams)
Equation 2: B = N + 5 (there are 5 more bracelets than necklaces)
These equations can be used to determine the number of bracelets and necklaces made.
