Mr. Spears was purchasing supplies for his math classroom. He had $25 to spend. Mechanical pencils and erasers come in bundles of 10. Each eraser costs $0.50. Fill in the missing place in the equation to compute the cost of each mechanical pencil.(1 point)
____(x + 0.50)=25
We need to find the missing number in the equation in order to compute the cost of each mechanical pencil.
The equation is:
____(x + 0.50)=25
We know that each eraser costs $0.50. Therefore, the cost of a bundle of 10 erasers is 10 times the cost of one eraser, which is 10 * 0.50 = <<10*0.50=5>>5 dollars.
So we can rewrite the equation as:
5 + (x + 0.50) = 25
Now we can solve for x:
5 + x + 0.50 = 25
x + 5 + 0.50 = 25
x + 5.50 = 25
x = 25 - 5.50
x = 19.50
Therefore, the cost of each mechanical pencil is $19.50.
