Can somebody help me?

($8.09*s) + ($3.79*c)

$70.77

Step-by-step explanation:

First lets start with the equation and how to get it. Now we know the cost for satin fabric, which is $8.09, and we know that the chosen variable is s. Since it is "per yard", we know we will be multiplying. So now we set it up

$8.09*s

Now lets start with the cotton fabric. We know that the cotton fabric costs $3.79, and the chosen variable is c. Once again, it is per yard so we are multiplying.

$3.79*c

We now have the equation for each fabric so now we can put it together.

$8.09*s + $3.79*c

And that is the final equation. If you want, you can add parenthesis to separate it more. This is optional ONLY since they are already separated by a "+"

($8.09*s) + ($3.79*c)

The second question answer is $70.77, not sure about the first question.
