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

i said fill in the blank

My apologies for the confusion. To fill in the blank, we need to solve the equation to find the value of x.

(x + 0.50) = 25

To isolate x, we need to subtract 0.50 from both sides:

x = 25 - 0.50

Simplifying this equation, we find:

x = 24.50

Therefore, the cost of each mechanical pencil is $24.50.

A school plans to spend twice the amount it did last year on its winter dance, less the cost of the disco ball which was $150, since they have it from last year. A total of $1,500 is being spent this year. Fill in the blanks to write an equation that will determine the amount of last year’s budget, a .(2 points)
