Bracelets Necklaces Total sales

November 15 8 $500

December 19 24 $980

What was the price of each item?

Bracelets cost $____

each and necklaces cost $____

Answer 1

Bracelet cost = b
Necklace cost = n

15b + 8n = 500
19b + 24n = 980

Elimination method x -3
-45b - 24n = -1500
19b + 24n = 980

-26b = -520
b = $20 bracelets

Plug back in
19(20) + 24n = 980
380 + 24n = 980
24n = 600
n = $25 necklaces


Check:
15(20)+ 8(25)= 500
300 + 200 = 500
500 = 500 :)
