To find the width \( w \) of each wood strip, you can use the equation that relates the total width of the finished coaster to the width of each individual strip:
\[
7w = 3.5
\]
This equation states that the width of the coaster (3.5 inches) is equal to the width of each strip (w) multiplied by the number of strips (7).
Now, to solve for \( w \), divide both sides of the equation by 7:
\[
w = \frac{3.5}{7}
\]
Calculating the right side:
\[
w = 0.5
\]
Thus, the width of each wood strip is:
\[
\boxed{0.5} \text{ inches}
\]
\[
7w = 3.5
\]
This equation states that the width of the coaster (3.5 inches) is equal to the width of each strip (w) multiplied by the number of strips (7).
Now, to solve for \( w \), divide both sides of the equation by 7:
\[
w = \frac{3.5}{7}
\]
Calculating the right side:
\[
w = 0.5
\]
Thus, the width of each wood strip is:
\[
\boxed{0.5} \text{ inches}
\]
