3)A book store, soft cover's price is $2/copy, hardcover's price is$5/copy. one day, 50 copies are sold, and the number of hardcover
sold is no less than 20, but no more than 30. How much money S generated from the sales?

30>=HC>=20

consider the extreme cases
(1) HC=30, SC=20 S=30*5+20*2=150+40=190
(2) HC=20, SC=30 S=20*5+30*2=100+60=160

so, 160<=S<=190

(2) includes this interval.

stol,for the first one you say A.can you explain.
slope = change in y / change in x.

y1/x1 > y2 /x2..... it can be that y2 > y1 then it will be A,if the X varies,then how can it be A?
just thinking loud, statement should be insuff.
