A store selling ribbon by the yard Mike bought eight yards of red ribbon each yard cost $3.50 complete and solve the working equation that represents the amount a my paid for buying 8 yd of ribbon

Let x be the amount that Mike paid for buying 8 yards of ribbon.

The cost of each yard of ribbon is $3.50.
The total cost is the cost per yard multiplied by the number of yards: x = 3.50 * 8.
Simplifying: x = 28. Answer: \boxed{28}.

To calculate the amount Mike paid for buying 8 yards of ribbon, we can set up the equation:

Cost = Price per yard * Number of yards

In this case, the price per yard is $3.50, and Mike bought 8 yards of ribbon. Plugging these values into the equation, we have:

Cost = $3.50 * 8

Simplifying the equation, we get:

Cost = $28

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

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

Total cost = Cost per yard * Number of yards

In this case, the cost per yard is $3.50 and the number of yards is 8. Therefore, the equation would be:

Total cost = $3.50 * 8

To solve this equation, we simply multiply $3.50 by 8:

Total cost = $28

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