The jeweler made 7 bracelets and 9 necklaces .
In the question ,
it is given that
amount of gold in each bracelet is 6 grams
amount of gold in each necklace is 24 grams .
let the number of bracelets "b" .
let the number of necklaces "n" .
since the total number of necklace and bracelet is 16 .
the equation is b + n = 16
so , b = 16 - n
also given that total gold used is 258 grams .
so the equation is 6b + 24n = 258
Substituting b= 16 - n in the equation ,
we get , 6*(16 - n) + 24n = 258
96 - 6n + 24n = 258
96 + 18n = 258
18n = 258 - 96
18n = 162
n = 162/18
n = 9
and b = 16 - 9 = 7
Therefore , The jeweler made 7 bracelets and 9 necklaces .
