To find out how many erasers Stefanie bought, we can set up an equation based on the total amount she spent.
Let \( x \) be the number of erasers she bought. The cost of the pencils is \$1.75, and the cost of the erasers is \( 0.25x \). The total cost for the pencils and erasers is given as \$4.25.
We can set up the equation as follows:
\[
1.75 + 0.25x = 4.25
\]
Now, we will isolate \( x \). First, subtract the cost of the pencils from both sides:
\[
0.25x = 4.25 - 1.75
\]
Calculating the right side:
\[
0.25x = 2.50
\]
Next, divide both sides by 0.25 to solve for \( x \):
\[
x = \frac{2.50}{0.25}
\]
Calculating this gives:
\[
x = 10
\]
Thus, Stefanie bought **10 erasers**.
Let \( x \) be the number of erasers she bought. The cost of the pencils is \$1.75, and the cost of the erasers is \( 0.25x \). The total cost for the pencils and erasers is given as \$4.25.
We can set up the equation as follows:
\[
1.75 + 0.25x = 4.25
\]
Now, we will isolate \( x \). First, subtract the cost of the pencils from both sides:
\[
0.25x = 4.25 - 1.75
\]
Calculating the right side:
\[
0.25x = 2.50
\]
Next, divide both sides by 0.25 to solve for \( x \):
\[
x = \frac{2.50}{0.25}
\]
Calculating this gives:
\[
x = 10
\]
Thus, Stefanie bought **10 erasers**.
