Answer:
[tex]5\[/tex]
Step-by-step explanation:
Let x be cost of 1 eraser.
[tex]5 +4x=25[/tex]
[tex]4x=20[/tex]
[tex]x=5[/tex]
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
Step-by-step explanation:
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
The last thing you do is you divide it by 4 on both sides to isolate the variable.
x = 20/4 = $5
