Answer:
$1.26 per yard of ribbon
Step-by-step explanation:
Hello, I think I can help you with this
The unit rate is the price that you pay for a unit of product, It is given by:
![unit\ rate=\frac{total\ paid}{number\ of\ products} \\](https://tex.z-dn.net/?f=unit%5C%20rate%3D%5Cfrac%7Btotal%5C%20paid%7D%7Bnumber%5C%20of%5C%20products%7D%20%5C%5C)
in this case, all you have to do is put the values in the equation
Step one
Let
![6\frac{1}{2} =\frac{(6*2)+1}{2} =\frac{13}{2} =6.5](https://tex.z-dn.net/?f=6%5Cfrac%7B1%7D%7B2%7D%20%3D%5Cfrac%7B%286%2A2%29%2B1%7D%7B2%7D%20%3D%5Cfrac%7B13%7D%7B2%7D%20%3D6.5)
so, 6 1/2=6.5
total paid:$8.22
number of products=6.5 yards of ribbon
replacing
![unit\ rate=\frac{total\ paid}{number\ of\ products}\\unit\ rate=\frac{8.22}{6.5}unit\ rate=1.26](https://tex.z-dn.net/?f=unit%5C%20rate%3D%5Cfrac%7Btotal%5C%20paid%7D%7Bnumber%5C%20of%5C%20products%7D%5C%5Cunit%5C%20rate%3D%5Cfrac%7B8.22%7D%7B6.5%7Dunit%5C%20rate%3D1.26)
unit rate = $1.26 per yard of ribbon
I hope it helps, Have a great day
