17. 令消費( C ) = 100＋0.8(Y－T)；投資(I) = 100，政府支出(G) = 50，淨稅額(T) = 50，則均衡所得 (Y)為： (A) 1000 (B) 1020 (C) 1050 (D) 1030

1. To determine the concentration of analyte A, the sample is titrated with the titrant B. Since both A and B can absorb electromagnetic radiation of 550 nm, the end point is to be detected spectrophotometrically at 550 nm. The shape of the titration curve at 550 nm would most closely resemble which of the following?(A) (B)(C)(D)(E)
