0 -1350

1 -800

2 -350

3 0

4 250

5 400

6 450

7 400

for letter A i already got the answer the quadratic formula which is y=-50x+600x+350

B. create a specific algebraic model for profit as a function of the number of items sold.show your work and clearly define variables

C. the break-even point is when profit is zero. what is/are the break even points?explain your answer
