Answer:
no solution
Step-by-step explanation:
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 :)
