The principal of Lakeshore Middle School wants to buy mechanical pencils with the school name on them for the school store.

The pencils can be bought from Company P for $0.57 each, with free shipping.

The pencils can be bought from Company T for $0.54 each, plus $4.95 for shipping.

Which statement is true about purchasing pencils from these two companies?

• Only the cost model for Company P results in a linear graph.

• The graphs of the cost functions for each company will not intersect.

• Buying pencils from Company T is always more expensive than buying pencils from Company P, regardless of the number of pencils bought.

• The company with the least expensive option can only be determined once the number of pencils the principal wants to buy is known.

Enter the rate of change of the cost, in dollars, per snack packet purchased.

• 0.80 dollars per snack packet.

• 0.50 dollars per snack packet.

• 1.20 dollars per snack packet.

• 1.00 dollars per snack packet.

• The function decreases.

• The graph of the function does not form a straight line.

• The coefficient of x^2 is not 1.

• The function does not contain the point (0, 0).
