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

The amount Mike paid for buying 8 yards of ribbon can be represented by the equation:

a = 8 * 3.50

To solve for a, we can multiply 8 by 3.50:

a = 28.00

Therefore, Mike paid $28.00 for buying 8 yards of ribbon.

To find the amount Mike paid for buying 8 yards of ribbon, we can use the equation:

a = 8 * c

Where:
a = amount Mike paid
8 = number of yards of ribbon
c = cost per yard of ribbon

In this case, each yard of ribbon costs $3.50. So, we substitute the value of c into the equation:

a = 8 * 3.50

Now, we can solve the equation:

a = 28

Therefore, Mike paid $28 for buying 8 yards of ribbon.

To find the amount Mike paid for buying 8 yards of ribbon, you can use the equation:

a = 8 * 3.50

Explanation:
- The cost per yard of ribbon is $3.50.
- Mike bought 8 yards of ribbon, so you multiply the cost per yard by the number of yards he bought.
- The equation becomes: a = 8 * 3.50.
- By simplifying the equation, you get the result: a = 28.

Therefore, Mike paid $28 for buying 8 yards of ribbon.
