A store is selling ribbon by the yard Mike buy 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

Let's represent the amount Mike paid for buying 8 yards of ribbon as a working equation.

The equation is:
Amount Mike paid = Number of yards of ribbon * Cost per yard of ribbon

Let's fill in the values:
Amount Mike paid = 8 yards * $3.50/yard

Let's solve the equation:
Amount Mike paid = 8 * $3.50 = $<<8*3.50=28>>28

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