You bought a magazine for $5 and four erasers. You spent a total of $25. How much did each eraser cost? Let "e" represent the eraser and write an equation.

Answer 1

4 e = 25 - 5
4 e = 20
e = 5

Answer 2

25 - 5 = 4e

Solve for e.

Answer 3

4e + 5 = 25
e = 25 - 5 / 4
e= 20/4
e= 5

just to check:
5.4 + 5 = 25
20 + 5 = 25
