Hello!

We are going to figure out how many pencils you bought with our given information from the question.

From the questions, we were given:

  • You spent $25 in total
  • You bought a book for $8.50
  • Each pencil cost $0.25

With the information given, we can set up an equation using our given information to help find how many pencils you bought.

We will use the form: y = mx + b where:

  • y = total spent
  • m = cost of pencil
  • x is the amount of pencils bought
  • b the cost of the book

When we insert our values into the equation, we would get:

25 = 0.25x + 8.50

Now, to find how many pencils you bought, solve for x:

Solve:

25 = 0.25x + 8.50

Subtract 8.50 from both sides.

16.50 = 0.25x

Divide both sides by 0.25

66 = x

This means that you bought 66 pencils.

Answer:

66 pencils.
