Question

1)Gabrielle is given the choice of two positions,the first paying $6400 per month and the other
paying $4000 per month plus a 5% commission on all sales made during the month.
What amount of sale must she make a month for the second position to be more profitable?

2)Create the function which best describes the graph shown below. (in image)

Part A

Find β such that the equation βx
2 + x + β = 0 has a repeated real solution.

Part B

The profit for Cocoa Board cocoa beans is given by Π(x) = −15x
2 + 180x − 405
thousand dollars, where x is the number of tonnes of cocoa beans produced and sold.
How many tonnes must be sold for to not make a loss?
