a=_____dollars

1 answer

To find the amount Mike paid for buying 8 yards of ribbon, we can multiply the cost per yard by the number of yards purchased.

Cost per yard: $3.50
Number of yards purchased: 8

Let's complete and solve the equation:

a/8 = 3.50

To solve for 'a', we can multiply both sides of the equation by 8:

8 * (a/8) = 8 * 3.50

This simplifies to:

a = 28

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