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

Solve and write an algebraic equation for it.
ALL 5 STARS AND THANKS!!

Each Eraser was equal to 5 dollars.

5 + 4x = 25

-5 on both sides.

4x = 20

/ 4 on both sides.

x = 5.

So your equation is 5 + 4x = 25 and your answer is 5 dollars per eraser.

Magazine cost: 5$ each

Eraser cost: X$ each

Total cost is the number of items (1 magazine) times the cost of each item (5$). We don't know the cost of each eraser, so we represent that using a variable, X.

1(5) + 4(X) = 25

5 + 4X = 25

subtract 5 from both sides

4X = 25 - 5

4X = 20

divide both sides by 4

X = 20/4

X = 5

Each eraser cost 5$
