A jeweler had a fixed amount of gold to make bracelets and necklaces. The amount of gold in each bracelet is 5 grams and the amount of gold in each necklace is 16 grams. The jeweler used 130 grams of gold and made 5 more bracelets than necklaces. Write a system of equations that could be used to determine the number of bracelets made and the number of necklaces made. Define the variables that you use to write the system.

1 answer

Let's use the variables B for the number of bracelets made and N for the number of necklaces made.

From the problem, we know that the amount of gold used can be determined by multiplying the number of bracelets made by 5 and the number of necklaces made by 16, so we have the equation:

5B + 16N = 130

We also know that the number of bracelets made is 5 more than the number of necklaces made, so we have the equation:

B = N + 5

Thus, the system of equations that could be used to determine the number of bracelets made and the number of necklaces made is:

5B + 16N = 130
B = N + 5
