What is the cost per marker if 8 markers cost $10.40?

Explanation:
Dividing the total cost by the number of items gives the price for one item. So, 10.40 dollars for 8 markers means 10.40 ÷ 8 = 1.30 dollars per marker. Therefore the cost per marker is $1.30. Quick checks: 8 × 1.00 = 8.00, 8 × 1.60 = 12.80, 8 × 1.20 = 9.60, none of which match the total of 10.40.
