Answer:
Diane has a booth at the state fair that sells bags of popcorn she has found that her daily costs are approximated by the function c(x) =x squared -20x+150
a) How many bags of popcorn must Diane sell to minimize her cost?
b) What is Diane’s minimum cost?
a) 10
b) 50
Step-by-step explanation:
According to the quadratic equation given in the question ,
the cost will be minimum at
comparing x^{2} -20x+150[/tex] with the standard quadratic equation
we get
a= 1, b = -20, c=150
now
Hence to minimize her cost, she must sell
a) x= 10 popcorns
and her minimum cost is
b)
Answer:
80x2=160 20x3=60 160+60=220
