Deiondre spent $20.60 for 4 spokes and 2 inner tubes. The inner tubes cost $8.50 each. The sales tax on the total purchase was $1.37. He also used a coupon for $0.75 off the purchase. If each spoke cost the same, how much did each spoke cost?

Respuesta :

8.5x2=17
20.6-17=3.6
3.6-1.37=1.23
1.23-0.75=0.48
0.48/4=0.12
the spokes cost $0.12 each
