The equation to compute the cost of each mechanical pencil is:
10(x + 0.50) = 25
First, we distribute the 10 to both terms inside the parentheses:
10x + 5 = 25
Then, we subtract 5 from both sides to isolate the term with the variable:
10x = 20
Finally, we divide both sides by 10 to solve for x:
x = 2
Therefore, each mechanical pencil costs $2.
