  1. Let R be the total rosebuds.
    Rosebuds bloomed= rosebouds-notbloomed
    3/14 * R+ 2/5(11/14)R = R-66

  2. Let N be the total number of rosebuds in the beginning. Turn the word statement into an equation.

    (3/14) N + (2/5)(11/14)N + 66 = N

    Now solve for N
    (15/70 + 22/70)N + 66 = N
    (33/70)N = 66
    N = 140

    Today, 22/70 of that number bloomed.
