New carpeting can be purchased and installed for $22.00 per square yard, plus a $50 delivery fee. (a) Write an equation that gives the cost, c, to carpet “s” square yards.
Wouldn't the equation for this be s = 22c + 50? I also need to find the inverse of this in order to calculate how many square yards are given for a certain price and the inverse of this equation: c - 50/22 = s is the only thing that makes sense.
Thanks
