Marvin and Alicia are putting new carpet in their living room. The carpet costs $4.15 per square foot and $97 to have it installed. Their total bill before sales tax is $1798.50. whats the equation?
I assume you'd like to find the square footage....we have
Cost of carpet + Installation charge = Total Cost
4.15s + 97 = 1798.50 where s is the square footage ....subtract 97 from both sides
4.15s = 1701.50 divide both sides by 4.15
s = 410 square feet
Your finally on! There is someone on here posting very inappropriate comments and answers. I'm afraid to say I know who it is, but they are as a "guest"
