What is the cost of each eraser if you bought a magazine for $5 and four erasers for a total of $25?

1 Answer

The buyer bought four erasers and a magazine for $25.

The cost of each magazine is $5

The cost of an eraser is x dollars

The cost of 4 erasers is 4x

Cost of the Erasers + Cost of the Magazine = Total Cost

4x + $5 = $25

Subtract 5 from both sides to isolate the term with the variable.

4x + 5 -5 = 25 -5

4x = 20

Divide by 4 on both sides to isolate the variable.

x = #20/4# = $5
