To find the total amount \( a \) that Might will pay for buying 8 yards of ribbon, we can set up the equation based on the cost per yard.
- The cost per yard of ribbon is $3.50.
- Might bought 8 yards of ribbon.
The total cost \( a \) can be calculated using the equation:
\[ a = \text{(cost per yard)} \times \text{(number of yards)} \]
Substituting the given values:
\[ a = 3.50 \times 8 \]
Calculating this gives:
\[ a = 28 \]
Now, according to your format:
- \( a/8 = 3.50 \)
- \( a = 28 \) dollars
So, the completed equations are:
- \( a/8 = 3.50 \)
- \( a = 28 \) dollars.
