Answer:
21 necklaces and 16 bracelets
Step-by-step explanation:
Number of jewelry sold
we can make use of variables :
b = bracelets
n = necklaces
we can create two equations with the information given:
2b + 3n = 95
b + n = 37
we can solve this by using elimination method:
firstly we need the values of (b) to be the same.
2(b + n = 37)
this gives :
2b + 2n = 74
now use this equation with the first one and use the elimination method.
2b + 3n = 95
2b + 2n = 74
the (2b) is cancelled out
3n - 2n = 95 - 74
n = 21
we can input the value of (n) into the original second equation to get the value of b.
b + n = 37
b + 21 = 37
b = 37 - 21
b = 16
they sell 21 necklaces and 16 bracelets
