Question 1:A plant can manufacture 50 tennis rackets per day for a total daily cost of $3855 and 60 tennis rackets per day for a total daily cost of $4245.

a) Assuming that daily cost and production are linearly related, find the total daily cost of producing "x" tennis rackets.

b) Graph the total daily cost for0100

c) Interpret the slope and y-intercept of this cost equation.

Question 2:At a price of $1.94 per bushel, the supply of corn is 9800 million bushels, and the demand is 9300 million bushels. At a price of $1.82 per bushel, the supply is 9400 million bushels, and the demand is 9500 million bushels.
