A jeweler had a fixed amount of gold to make bracelets and necklaces. The amount of gold in each bracelet is 7 grams and the amount of gold in each necklace is 20 grams. The jeweler used 109 grams of gold and made 4 more bracelets than necklaces. Determine the number of bracelets made and the number of necklaces made

#Necklace = x

   Then  #Bracelets = x +4

 

amount of necklace gold  =   20*x

amount of gold in bracelet = 7*(x+4)     added together = 109 gm

 

20x    +  7(x+4)     =    109       solve for 'x' = number of necklaces    then bracelets = x+4
