Snowing in Centimeters

It snowed yesterday in New York, Winnipeg, Boston, and Toronto. Each city had a different amount of snow accumulation. Figure out how much it snowed in each city.

Assume 1 inch = 2.54 centimeters.
(numbers in clues are rounded to the nearest hundredth)
  1. Boston and Winnipeg had a total accumulation of thirty-six and thirty-two hundredths centimeters.
  2. New York and Winnipeg had a total accumulation of thirty-three and seventy-eight hundredths centimeters.
  3. Winnipeg had two times more snow than Toronto.
  4. New York and Toronto had a total accumulation of ten and fifteen hundredths inches.

    Still rounding things to the nearest hundredth:

    New York = 17.78 cm
    Winnipeg = 16.00 cm
    Boston = 20.32 cm
    Toronto = 8.00cm

    From the question we get the following equations:

    B+W=36.32
    N+W=33.78
    N+T=25.78 (Converted Inches to Centimeters)
    W=2T

    Now,
    Subsitute eq 4 in Eq. 2, we get
    N+2T=33.78

    Solve the above eq with eq. 3, we get
    T=8
    W=16
    N=17.78
    B=20.32

    As usual, you impress me with the answers you give. I can't add anything else to your explanation.
