Answer 1

Ms. Rao Pays $1890 for the computer Price of Computer(C) + Printer(P) + Scanner (S) = $2543 Price of Computer: C = 1502 + P Price of Printer: P = 123 + S So Price of computer now becomes: C = 1502 + 123 + S (Here we replace P with 123 + S) It is Algebra from here: C + P + S = 2543 (1502 + 123 + S) + (123 + S) + S = 2543 1748 + 3S = 2543 3S = 2543-1748 3S = 795 S = 795/3 S = 265 C = 1502 + 123 + S C = 1502 + 123 + 265 C = $1890 Ms. Rao pays $1890 for the computer
