A store is selling rib ion by the yard. Mike bought 8 yards of red ribbon each yards cost $3.50. Complete and solve the working equation that represents the amount,a, Mike paid for buying 8 yards of ribbon

Answer 1

To find the total amount \( a \) that Mike paid for buying 8 yards of red ribbon at a cost of $3.50 per yard, you can use the equation:

\[ a = \text{(cost per yard)} \times \text{(number of yards)} \]

In this case:

\[ a = 3.50 \times 8 \]

Now, calculate the total amount:

\[ a = 3.50 \times 8 = 28.00 \]

Thus, the amount \( a \) that Mike paid for buying 8 yards of ribbon is:

\[ \boxed{28.00} \]
