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
