Consider the three stocks in the following table. P_t represents price at time t, and Q_t represents shares outstanding at time t. Stock C splits two for one in the last period.

	P0	Q0	P1	Q1	P2	Q2
A	75	350	80	350	80	350
B	55	800	50	800	50	800
C	60	900	70	900	35	1,800

a. Calculate the rate of return on a price-weighted index of the three stocks for the first period (t = 0 to t = 1). (Do not round intermediate calculations. Round your answer to 2 decimal places.)
