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:

$$\boxed{{\displaystyle 28.00}}$$
