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:
