    You bought a magazine for $5 and four erasers. You spent a total of $25. How much did each eraser cost?

    Calculate the cost of all erasers:
    Cost of all erasers = Total Spend - Magazine Cost
    Cost of all erasers = 25 - 5
    Cost of all erasers = 20

    Calculate the cost per eraser:
    Cost per eraser = Cost of all erasers / Total erasers
    Cost per eraser = 20 / 4
    Cost per eraser = Cost of all erasers / Total erasers
    Cost per eraser = $5
