$32 + $63 = $95

Answer 2

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
