Mr. Spears was purchasing supplies for his math classroom. He had 25$ to spend. Mechanical pencils and eraser come in bundles of 10. Each eraser cost 0.50. Fill in the missing place in the equation to compute the cost of each mechanical pencil

Question

__ (x+0.50)=25

Answer 1

Let's represent the cost of each mechanical pencil as "y".

Since each eraser costs $0.50 and there are bundles of 10, the equation for the cost of erasers would be 10(0.50) = $5.

To find the cost of the mechanical pencils, we subtract the cost of erasers from the total amount Mr. Spears had to spend: $25 - $5 = $20.

Now, we can set up the equation to find the cost of each mechanical pencil:
10y = $20

To isolate "y", we need to divide both sides of the equation by 10:
10y/10 = $20/10

Simplifying the equation gives us:
y = $2

Therefore, the cost of each mechanical pencil is $2.
