Mike bought 8 yards of ribbon. Each yard cost 3.50. Complete and solve the working equation that represents the amount, Mike paid for buying 8 yards per ribbon.
Amount paid = cost per yard * number of yards
Let's represent the amount paid by P, the cost per yard by C, and the number of yards by Y.
From the given information, we have:
P = C * Y
Substituting the given values:
P = 3.50 * 8
P = 28
Therefore, Mike paid $28 for buying 8 yards of ribbon.
