Mr. Spears was purchasing supplies for his math class. he has $25 dollars to spend. mechanical pencils and erasers come in bundles of 10. each eraser costs $0.50. fill in the missing place to complete the equation of how much the pencils cost
Let's assume the cost of each bundle of mechanical pencils is $x.
Since each bundle of mechanical pencils comes in a bundle of 10, the cost of a single mechanical pencil would be $x/10.
To find the total cost of pencils, we need to multiply the cost of a single pencil by the number of pencils (10).
Therefore, the equation to represent the cost of the pencils is:
Total cost of pencils = (cost of a single pencil) * (number of pencils)
25 = (x/10) * (10)
Simplifying the equation, we have:
25 = x
Therefore, the cost of the pencils is $25.
