Alex bought some notebooks that each cost $4, plus a $5 supply fee. If the total was $29, write an equation to find how many notebooks Alex bought.Alex bought some notebooks that each cost $4, plus a $5 supply fee. If the total was $29, write an equation to find how many notebooks Alex bought.

Answer 1

Let \( n \) represent the number of notebooks Alex bought. The cost of the notebooks is \( 4n \) dollars, and the supply fee is $5. The total cost is given as $29.

We can set up the equation as follows:

\[ 4n + 5 = 29 \]

To solve for \( n \), first subtract 5 from both sides:

\[ 4n = 29 - 5 \] \[ 4n = 24 \]

Now, divide both sides by 4:

\[ n = \frac{24}{4} \] \[ n = 6 \]

Thus, Alex bought 6 notebooks.
