1. The problem statement, all variables and given/known data Kaylas lemonade stand has experienced rises /falls in sales caused by temperature changes over 2 summers. Her sales over the first two weeks of summer were tracked according to the model S(x) = x^3 -12x^2 +36x, where x is the number of days and S(x) is the number of sales. a) Kayla makes a profit if she sells atleast 10 glasses of lemonade. use the model to determine the number of days that she made profit. b) What is the domain/range c) describe the weather for the summer in terms of her lemonade sales model. Predict the number of sales on her last sales day (aug31) does this seem reasonable? 2. Relevant equations 3. The attempt at a solution How do you solve this? Ive tried grouping and factoring but the discriminant is = 0 , IM not sure what to do The factor would be (x-6)^2 . If you group its x^2-12x +36 which is (x-6) (x-6) . Dont think thats what your supposed to do anyway. Anyone know how to solve?
