When = 50, TFC = $2,000, and TVC = $8,000. When Q = 60, TVC = $9,000. Which of the following is true?

a.It is impossible to knowTCwhenQ=60because we are not givenTFCwhen Q=60.

b.IfTVCincreased by $1,000, thenTFCmust have increased by $1,000 also, so whenQ=60,TC=$12,000.

c.IfTVCincreased by $1,000, thenTFCmust have decreased by $1,000 to keepTCconstant.

d.When Q=50,TC=$10,000and whenQ=60,TC=$11,000.
